Looking for a graphing calculator, matrix support, or simply want to support the cause of creating the greatest scientific calculator app on Android? Get MathsApp Graphing Calculator: https://play.google.com/store/apps/details?id=com.mathsapp.graphing
MathsApp Scientific Calculator includes:
-Easily adjust previous calculations or insert previous results
-Binary, octal and hexadecimal number support
-Scientific, engineering and regular number formatting
-Advanced statistical distribution functions
-Complex number support
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.

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 (firstname.lastname@example.org).
NOTE: If you upgrade to Android 5.0+, reinstall the app to continue using offline calculations.

It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function.
Eg f (x) = x ^ 2 + x, after insertion, type f '(x) to display the graph of the derivative.
To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";".

"BisMag Scientific Graphing Calculator 3D"is a demo version of "BisMag Calculator 3D" if the product is to your liking and you find it useful try the PRO version.
scientific calculator, scientific calculator app, grapher, graphic calculator, integration, derivative, mathematica, matlab, mathcad, complex numbers, plotting, graph plot, plotter, calculation, symbolic calculations, graphing calculator, study of function, asymptote, derive, arity, symja
This is a re-work of our famous MathScript calculator. The current pre-release alpha version is intended to test the framework and receive user feedback (please scroll to FAQ at the end to see guidelines for feedback).
Nexus 7 users: We do not yet know what is causing the poor app response. Kindly bear with us till we get hold of a Nexus 7 device.
If you find any issues, kindly mail us. Please do not give bad rating. The entire suite of (full version) software will be free and it would be counter productive if the bad rating prevents users from testing it and providing feedback.
Initial loading is slow only for first time. Subsequent loading should take less than 5 seconds (2 sec. in HTC OneX/GalaxyNote)
* Complete scientific suite of calculations similar to mathematica and matlab using SymPy and NumPy libraries
* Graphical representation of equations with our smart typesetting mechanism
* Full graphical shell using Kivy framework
* Publication quality plots through the awesome plotting library "matplotlib"
Note: We haven't yet completed the feature list. More features will be added with each update.
The help system is not implemented fully. So, for now you are on your own to find out certain stuff. But, the system is supposed to be intuitive. Let us know if some things are not evident immediately :)
Thanks for your support.
* I found a problem not listed here
Please mail us ASAP! We are waiting for your feedbacks and suggestions and work on the improvements based on those.
* How can I contribute?
Currently, we are expecting feedbacks from users to let us know about the feel of the system. You can contribute by just using the app and letting us know if it works well on your system.
* The app is crashing when I open it.
Please check if you have around 80 MB free space before installing the app. Some times, the problem could be due to insufficient space in your memory. We will be grateful if you can get a log output and share it with us.
* The app crashed! How to let you know about it?
System logs can be very valuable in providing crash reports. You can access the log and mail it to us using the free third party app: "aLogCat".
* Why is it slow?
The app is targeted at next generation devices. The slight lag in graphics and delay in computations are visible only in previous generation devices and is almost instant with devices such as HTC One X, Galaxy S3, Note etc..
Also, loading a big program would consume some time. So, please save and close the programs when not needed. Please try to avoid creating very large programs.
* How to share files to others?
The files are located at the folder "MathSysData" in your external storage. You can share using any file browser.
* Help button is not working
For getting help, focus on a function (you will see a frame surrounding it when focussed) and click help. For some functions, the help system might not be available. We will be adding supporting documents gradually.
* Can I develop custom functions?
Yes. You can do complete Python programming. However, much more need to be done to make it user friendly.In future, you will be able to develop your own functions, their graphical representations and even your own keypad set.
* Will this be available in other platforms?
The first release is for Android. Once the product matures, we will release versions for iOS, Mac, Linux and Windows.
Motorola Xoom 2
HTC Evo 3D
HTC One X
Samsung Galaxy SIII
Samsung Galaxy Note

This app is no longer the plotting engine for Octave. Get the Octave Gnuplot Package instead (com.octave.gnuplot).
A Computing Environment useful for solving many complex problems.
A Matlab / Octave clone for Android.
Java based and open source.
Free and Ad free.
Has most needed math capabilities.
A lot of function included already.
Can parse and run .m files. (try "edit /sdcard/test.m")
Working on bugs and compatibility.
Basic plotting working (you need the app called AddiPlot).
Custom keyboard for entering commands faster.
Now have Octave built for Android, moving this soon to a separate app called "octave" (clever...I know). You can go checkout the first version soon. Addi will be going back to being solely java based and small and not very feature rich, while octave will be the real deal, but much larger.

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?
A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/
Q. How do I get to the keys for pi, e, solve, etc?
A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.
Q. What do you have planned for future releases?
A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!
