Works I got this to work just fine, but this trial doesn't even give me enough time to evaluate whether or not I like the program. I understand it is cheap, but I can't try it out for more than 30 seconds before it cuts me off. How am I supposed to know if it can achieve what I would like it to. 3 stars because it works exactly like it should, but pretty poor way to try to let someone evaluate a product.

Great Thanks

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/.

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/

## 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.

## Wireless IMU

This app sends the measurements from your phone inertial sensors via UDP as CSV (Comma-Separated Values) to a computer in your network.

This turns your phone into a wireless inertial measurement unit (IMU).

This turns your phone into a wireless inertial measurement unit (IMU).

The following sensors are supported:

- Accelerometer

- Gyroscope

- Magnetometer

If your phone has not all these sensors, only the available sensor data is transmitted.

Example UDP packet:

890.71558, 3, 0.076, 9.809, 0.565, 4, -0.559, 0.032, -0.134, 5, -21.660,-36.960,-28.140

Timestamp [sec], sensorid, x, y, z, sensorid, x, y, z, sensorid, x, y, z

Sensor id:

3 - Accelerometer (m/s^2)

4 - Gyroscope (rad/s)

5 - Magnetometer (micro-Tesla uT)

You can run this app in the background.

A warning dialog appears, if you are not connected to a WiFi network.

In the example video, the stream is directly processed by a MATLAB script for Kalman Filtering. But it's up to you, what you do with the data.

With the following Python script you can capture the UDP data stream from your phone:

# -------------------------------------------------------

import socket, traceback

host = ''

port = 5555

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)

s.bind((host, port))

while 1:

try:

message, address = s.recvfrom(8192)

print message

except (KeyboardInterrupt, SystemExit):

raise

except:

traceback.print_exc()

## FIR Filter Designer

The FIR Filter Designer app designs minimal-order finite impulse response (FIR) digital filters based on performance specifications you provide. The application attempts to find the lowest order (smallest) set of FIR filter coefficients that satisfies the given specifications. The generated filter has approximately unity (0 dB) gain in the passband.

The output of the design procedure is a list of double-precision filter coefficients (Text output option) or an implementation of the filter in C/C++, C#, Java or MATLAB/GNU Octave source code. This output is formatted into an email you can send to any recipients.

Complete source code for the Android FIR Filter Designer app is available at https://www.assembla.com/code/firdesign/subversion/nodes.

Thanks to Jake Janovetz for providing a GPL-licensed implementation of the Parks–McClellan algorithm that served as a starting point for this app.
