29 Oct 2013 Simulink Support Package for LEGO MINDSTORMS NXT hardware (R2012a) Simulink block library for creating models that run directly on yourLEGO MINDSTORMS NXT robot Author: MathWorks Simulink Team

Johanna, what platform are you on? This support package is only for Windows. Also, on Windows, if you type "targetinstaller" and choose "Internet", you should able to install the LEGO NXT support.

Muthu, it is possible to use the widgets without blocking MATLAB. See examples/autodemo2.m and autodemo3.m

01 Oct 2012 Embedded Coder Target for Arduino Custom target for Arduno and other processors Author: MathWorks Embedded Coder Team

Aditya, the C code for S-functions and corresponding TLC files are in the "blocks" directory. For more info on creating custom blocks: see http://www.mathworks.de/de/help/simulink/user-defined-functions.html

11 May 2012 Simulink Support Package for Arduino Uno Hardware (R2012a) Simulink block library for creating standalone applications for the Arduino® Uno platform Author: MathWorks Simulink Team

uluc: This support packages requires R2012a and Simulink. If you have these, type "targetinstaller" at the command line and follow the instructions (the support package will be downloaded automatically).

06 May 2012 Simulink Support Package for Arduino Uno Hardware (R2012a) Simulink block library for creating standalone applications for the Arduino® Uno platform Author: MathWorks Simulink Team

Manas, targetinstaller and associated support packages are new features in R2012a. They are not supported in earlier releases.

12 Jul 2014 EasyGUI EasyGUI ver 1.0 -- Build GUIs quickly and easily in MATLAB Author: Gautam Vallabha Metcalf, Andrew

I am having a problem setting the TitlePosition to anything but 'lefttop' on a gui.group. It throws an error on line 65 of borderedwidget.m.

Any ideas on how to fix this? Thanks.

Please, never mind my previous comment. It is completely all right in the code. Sorry about the confusion.

02 Jul 2014 PLOT_GAUSSIAN_ELLIPSOID Plots two- and three-dimensional Gaussian distributions Author: Gautam Vallabha Iglesias, Fernando

There seems to be a small error with large consequences in the computation of the ellipsoids.

Basically, when you use the matrix of eigenvectors (v) and eigenvalues (d) to perform the rotation of ap as (v*d*ap), you should be using the square root of the eigenvalues. That is, the rotation should be (v*sqrt(d)*ap).

You can convince yourself that there is something wrong if the square root is not applied by computing the Mahalanobis distance from the mean to the points of the ellipsoid. This distance must be constant for all the points of the ellipsoid, and it is not unless you take the square root.

Thanks for your sharing your function!

18 Jun 2014 ECRobotInstaller – Simplified installation of tools for Embedded Coder Robot Simplifies the installation of ECRobot, a Simulink platform for LEGO Mindstorms NXT code generation Author: Gautam Vallabha Christian

Did anybody figure out how to solve this problem with make? I think my 64-Bit Windows 7 might be a problem...
I'm using MATLAB R2014a, 32 Bit.

Elapsed real time is what I'm searching for. Very nice implementation. Superb.

Thank you very much for sharing.
