Nice Matlab style calculator Scientific calculator, small download size, for quick calculations works well. I don't need a full GNU Octave package for my phone so this is great.

Dem Ja

Compact but working very well. It is compact in size but works very well even with my 4-year old android device, which has a small screen size and very limited memories.

A Google User

Optimal There is such an abundance of calculator aps, that it is difficult to test all of them. However, this one is absolutely the best of those I tested. The command line input allows for an immediate translation of math formulas into answers. There is no point in reproducing cumbersome interfaces of standalone calculators that other aps try.

User reviews

Help is broken The help page has links to lists of functions grouped by category or by alphabetical listing. Clicking on either link attempts to load an internal resource which my phone's browser can't resolve. (Running on an HTC One X+, Android 4.1.1.) Also, the app initially brings up a page telling you where to find tutorial videos. One method is to follow a link (hosted by Google); the other is to open the Help menu in the app, but again, the links to this video are nonexistent on that help page.

Really good Six stars when I can buy an ad free version ;-)

Fascinated Really surprised, in fact it is a mini Matlab! very nice, fast and efficient. I would recommend it to anyone looking for a good calculator. Well done developer, keep up the good work.

Awesome Doesn't play very nicely with physical keyboard. Still awesome!

Great app. Have just downloaded it and have just starting using it. Commands so similar to Matlab. So far a terrific app.

Ugh, another initially force-closing app... not worth the time, people.

Good work Keep it up. Please add mfile suppot and improvement in plotting.

Great program Great updates coming up recently. Love the plotting customization and m file support, looking forward for more functions.

Nice app, finally something for inverting my matrices on the go. Easy to enter matrices, but limited documentation on functions.

Would get 5 stars if it solved for unknown variable I was hoping for something like Mathlab that solves for unknowns. It does forward calculations but it would be great if it could calc yield from price

Y u no support physical keyboard? Input with physical keyboard is not working under Android 3.2 on an Asus Transformer. Besides, niec project you are working on.

Please release a paid-for version so I can use this without ads.

Matrix calculations should be possible. 5 stars if it had this feature

Very nice! Adding more functions with updates to become a mini matlab.

Doesn't remember variables! Could be good if only it would remember variables. Writing a=1, hitting enter, then writing a+1 and hitting enter should display 2, but instead nothing is displayed! I can't even start to test this as a mobile version of Matlab if it's not possible to store variables. Using a brand new Nexus S, Android 2.3.1.

I'd like to see a $1 version so I can get rid of the ads. Otherwise, this is an excellent tool.

It's like MatLab in your pocket! Almost. Add matrix functions like mean( ), std( ) (standard deviation), etc. and I will give 5 stars.

Wow. Portable Matlab in your pocket. I hope you can integrate scripts and coding for advance portable calculations. Will pay t support for development

Finally math tool for a series of computations. I am willing to pay to keep development going. Please go ahead!

Can this program actually manipulate matrices? As far as I can tell, the answer is no.

Has some computational bugs (try entering sqrt(-1) and it'll return a value with a real part), but it's good. Looking forward to updates.

## MATLAB Mobile

Note: To use MATLAB Mobile, you will need a MATLAB license that is current on MathWorks Software Maintenance Service.

Connect to MATLAB remotely from your Android smartphone or tablet.

MATLAB Mobile™ is a lightweight desktop on your Android device that connects to a MATLAB session running on MathWorks Cloud or on your computer. From the convenience of your Android device, you can run scripts, create figures, and view results.

Features

* Command-line access to MATLAB

* Access to MATLAB workspace

* Ability to view MATLAB figures on your Android device

* Record of commands typed on the device in your command history

* MathWorks Cloud connectivity and storage

* Windows, Mac, and Linux connectivity

* Acquire data from device sensors

Limitations

MATLAB Mobile does not support:

* MATLAB apps such as Curve Fitting or Signal Analysis

* Creating graphical interfaces using GUIDE

* MATLAB Editor

* Simulink graphical environment, but the 'sim' command is supported at the MATLAB Mobile command line

* Interaction with 3D figures

About MATLAB

MATLAB is the leading technical computing software for algorithm development, data visualization, data analysis, and numeric computation. MATLAB is used in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology.

Requirements

1. One of the following MATLAB licenses:

* Professional or academic license for R2012a or later with an up-to-date MathWorks Software Maintenance Service contract.

* MATLAB Student or MATLAB and Simulink Student Suite R2014a or later.

* MATLAB and Simulink Student Version R2012a or later.

* MATLAB Home.

2. MATLAB Connector installed on the same computer as MATLAB. Starting with R2013a, the MATLAB Connector will be installed with MATLAB. For R2012a and R2012b, download MATLAB Connector at http://www.mathworks.com/mobile/.

3. Android 4.0 or later

MATLAB Mobile and the MATLAB Connector are intended for use behind a firewall on a private network. Virtual Private Network (VPN) use is recommended when used over the public Internet or via 3G or 4G.

## Octave

This is launches Octave for Android. Octave is like Matlab (trademark of Mathworks), but free (as in freedom) software. Not some similar program, but really Octave running natively.

The app is now free (as in $) to use, but a donation is appreciated to keep things going.

You are required to get the Octave Main Package (com.octave.main) to use this.

You are required to get the Octave Gnuplot Package (com.octave.gnuplot) to support plotting.

There are many additional packages (com.octave.*) for use.

This is a different sort of app. Unpacking the executable and other files necessary for Octave to run will take awhile when you install or upgrade this, but will be worth it. Whether this is installed to the sdcard or to internal storage, the executables and libraries will take up around 100MB of internal storage either way.

You can add .m files and a .octaverc startup file in an external storage directory setup for you. Often at /sdcard/GNUOctave/home.

Your latest plots (.png files) can be found in an external storage directory setup for you. Often at /sdcard/GNUOctave/intents.

You will be running in a fake chroot of sorts which includes Octave and many of the programs you expect to find in a standard GNU/Linux (read Debian) install. The fake chroot is split between your external/shared partition (often /sdcard) and your internal (/data/data/com.octave) to save space.

Plot commands and edit commands fire off intents to use whatever image viewer or text editor you have.

See Octave Documentation:

http://www.gnu.org/software/octave/doc/interpreter/

See the FAQ:

https://github.com/corbinlc/octave4android/wiki/FAQ

## Symbolic

Symbolic is just another GUI for the immense powerful Reduce computer algebra system which is open source software created by many programmers during several decades. You may find lots of examples and tutorials about Reduce in the internet.

This app is based on code provided by Ahmad M. Akra and Prof. Arthur C. Norman (Codemist Ltd. JLisp, precompiled Reduce engine and most of the Latex formatting feature) who published the app AndroidReduce and made available the corresponding source code via sourceforge.net (great, many thanks!).

You may choose between single line and multiline input. In single line mode you may omit closing parentheses and/or the semicolon, but in multiline mode you have to take care of matching parentheses by yourself and explicitly type in a semicolon for telling Reduce that the expression is complete. Multiline mode is convenient for breaking down more complex expressions into several lines and always applies to reading script files. Processing starts when tapping the Go button (if visible) or the Done or Next button of the soft keyboard.

In Settings you find some options to modify the look of the output (preferred width, font size, text or latex).

You may process Reduce scripts stored in files (*.red or *.txt) with ease. Just enter a filename in the input field and tap menu-entry Read to execute it. Or save your precious work by tapping Save. When saving, the tex formatted output fields go to png-files with increasing numbers added to the original file name. But this only works for output fields not too big. Plain text outputs go to a text-file along with the corresponding input expressions. This may be useful for later processing the results in Latex or similar text processing tools.

If you do not know the exact filename containing your desired script just leave the input field empty (e.g. tap Clr button) and tap menu-entry Read to reveal a file selector box showing the files in the actually chosen directory.

Choosing a file only copies the filename to the input text field. Don\'t forget to tap Read again (or the Go button, if visible) to actually start processing the script file because you still have the option to add "in " before the filename to let Reduce process the whole file at once (what is mostly faster).

Tapping Clr or Go or Done during reading a script file will terminate processing the file. But the definitions realized so far stay valid in Reduce till you Reset Reduce.

The directory to read from or to save to may be defined via Settings. This global directory is also valid for in and out statements of Reduce itself. But nested input files do need complete pathnames along with "in" or "out" or "shut".

You may also modify some cosmetic features like background and text colors and the availability of the Clear and Go button which may support an efficient workflow. The settings get saved once you finish Settings with OK and are available next time you start the program.\n\n

So, happy calculating!

Please report bugs, questions and comments to Dieter Egger (dr.egger@alice.de).

## Scientific Calculator Plus

CYZ SOFT

1

Scientific Calculator Plus is a powerful mathematical tool to do mathematical analysis and evaluate complicated mathematical expressions similar to Matlab. More than Matlab, it has capability to take photo of printed math expressions and recognize them to do further analysis. It supports complex number, matrix, (higher level) integration, 2D, polar and 3D chart, string, programming (using a easy-to-use language called MFP), file operation and unit conversion. It can run in both Android phones and tablets, PC or MAC with JAVA ready (Scientific Calculator for JAVA does not support math recognition).

Main capabilities:

1. Math recognition: User enter into Smart Calculator and then click the camera button to take photo of one or more than one printed math expressions to recognize. User is able to choose to calculate or plot graph or simply use the recognized text as input. Comparing to Photomath, Scientific Calculator Plus is a bit slower at recognition speed. However, it supports a lot more expressions types than Photomath. And it is able to plot chart of expressions.

Scientific Calculator Plus supports the following expressions: 1. Addition; 2. Subtraction; 3. Multiplication; 4. Division; 5. Fractions; 6. Roots; 7. Multiple linear expressions; 8. Trigonometry; 9. Polynomials; 10. Exponents; 11. Algebra; 12. Integration; 13. Summation; 14. Product; 15. Matrix and 16. Complex value. User can also send email to us if the recognized result is not satisfactory.

2. Back-end math engine: Scientific Calculator Plus supports complex number, matrix, integration and is able to solve multi-variable linear equations, polynomials (up to 6 order) and other simple functions.

Example to input matrix: [[1,2],[3,4]], where [1,2] and [3,4] are 2 rows in the 2*2 matrix.

Example to input complex number: 8.71 - 5.44i where i is the image unit, the times operator, which is *, between 5.44 and i can be ignored. If ignored, no space is allowed between 5.44 and i;

Example to input integral: integrate("x**2", "x", 0, 1) (definite integral of x square from x = 0 to 1) or integrate("x**2","x") (indefinte integral of x square).

3. Graph engine: This app is able to plot 2D, plor or 3D chart. In smart calculator, user inputs the expressions and Scientific Calculator Plus automatically identifies the number of variables (2 variables means 2D chart or polar chart, depending on variable name; 3 variables results in 3D chart) in the expressions and draws corresponding graph. Scientfic Calculator Plus also provides stand alone tools to draw complicated graphs and a set of functions to draw charts from command line.

4. Programming: This app is actually a shell of programming language called MFP. This language internally supports string, complex number and matrix and is able to call all the built-in functions and all the user-defined libs stored in AnMath/scripts folder in SD card. This programming language also provides a complete set of file operation functions and time / date functions. Theoretically, user can do anything using this programming tool in an Android device.

Main components:

1. Smart calculator: User can take photo to recognize math (printed only), do any calculation or plot graphs using this tool. An internal calculator assistant can convert units and return constant values. Its input pad is configurable. User can add his/her own function buttons.

2. Command line: A matlab like tool for advanced users. User inputs functions line by line and run. Its key board is also configurable.

3. Integration and plotting graphs: Tools calculate complicated integrals and plot various graphs.

4. Scientific Calculator for JAVA: It is included in Scientific Calculator Plus for Android. User is able to connect the mobile device to any PC or MAC via a USB cable, copy SDcard\AnMath\ folder to his/her own directory and launch the JMathCmd.jar in it. Note that SCP for JAVA is not able to recognize math expressions.

Need ATE (android terminal emulator) installed before you install this to work - https://play.google.com/store/apps/details?id=jackpal.androidterm&feature=nav_result#?t=W251bGwsMSwxLDMsImphY2twYWwuYW5kcm9pZHRlcm0iXQ..

This app is no longer the plotting engine for Octave. Get the Octave Gnuplot Package instead (com.octave.gnuplot).

## Inard CAD

Inard was created with the vision to empower users to create CAD drawings with speed and ease. It combines the speed of the touch screen with efficient basic AutoCAD features.

Inard is not using a traditional AutoCAD interface since that will not work well on small screens. Use the interactive help to get you up and running quickly. Inard prompts the user with relevant actions dependent on what has been chosen on the screen and use sane defaults where possible. This approach does not clutter the interface and minimizes number of steps needed to achieve result. To reach full potential the user need to spend a few minutes to learn Inard CAD.

Inard supports lines, arcs, circles, rectangles, areas, text and distances. Double finger touch is used to support snap, near, and intercept selections. The basic editing features Copy, Move, Rotate and Delete are supported as well as the more advanced CAD features Extend, Fillet, Mirror, Offset, Trim, Split. Line widths, text heights, distances are adapting to the size of the drawing as it grows. Line type, line width, text height, and color can be modified by editing existing layers. Sharing the result as an Image, PDF, DXF or Inard file is done with a few clicks (Pro version only).

Some of these features are only supported in the pro version.
