01 Apr 2014 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*CdC
This software is only a small demo I wrote for fun, and never tested with more than one user.

Probably it is also not really suitable for multiple users, because Matlab is in basis single threaded.

A solution is using a real HTTP server like Apache, in combination with PHP (see easyphp.org).
Then compile your matlab-code to a executable and simply parse the user inputs/outputs to that executable through PHP.

21 Feb 2014 Patch Software Render Patch Software Render with Phong-shading, shadows and textures Author: Dirk-Jan Kroon

Note, in this version is the following bug
Line 34 in renderpatch_shading.cpp:
if(L[3]==0)
Is a bug, must be:
if(LP[3]==0)

Thank you, there was a bug which I solved by removing abs from the eigenvalues. This version will probably be online in one or two days.

11 Oct 2012 Web Server HTTP Matlab Web Server, allows m-files to be executed in a browser Author: Dirk-Jan Kroon

*Filipe S.
A Matlab GUI/Figure is user-interface thus client-side, this is a webserver thus server-side.
The only way to do client-side things like showing a GUI, is manually coding the GUI in javascript, html and css

17 Apr 2014 Accurate Fast Marching Multistencils second order Fast Marching 2D and 3D including rk4 shortest path and skeletonize Author: Dirk-Jan Kroon Yu, Nicolas

This work is good. But I have one suggestion that why not sort these vessel tree branches with bi-tree, so we are easy to show it consistently ?

13 Apr 2014 Kinect Matlab Microsoft Kinect, OpenNI wrapper, Skeleton, Depth Author: Dirk-Jan Kroon forrest, simba

works great with Matlab R2011a, Win7 64bit and OpenNI1.

When compile, use the short folder names:
OpenNiPathLib='C:\Progra~1\OpenNI\Lib64';
OpenNiPathInclude='C:\Progra~1\OpenNI\Include';

otherwise the compiler cl gives some error.
