plugin in Matlab

[Bas de Kruif]

Hello all,

Thanks for reading this post. I wrote a plugin for a controller and would like to use the model with this controller from within Matlab. The plugin works when I use it in OpenSim, but I cannot get the model to work in Matlab. I get stuck in the first step in which I try to load the plugin in Matlab.

There is already some information on this topic:

https://simtk.org/forums/viewtopic.php? ... tlab#p8878
https://simtk.org/forums/viewtopic.php? ... ary#p11969

However, this doesn't help me to get it to work. I have copied the files MyController.dll to the plugin directory of Opensim. Then I added the path to the plugin directory to librarypath.txt, and tried to load the dll with:

Code: Select all

loadlibrary('MyController.dll','C:\Users\bas\Documents\OSanalysis\controllerPlugin\MyController.h','includepath','C:\Program Files\OpenSim 3.3\sdk\include\')

As a result I get some warnings and errors:

Code: Select all

Warning: Function input has the same name as a MATLAB builtin. We suggest you rename the function to avoid
a potential name conflict.

C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\INCLUDE\eh.h(27) : fatal error C1189: #error :

Is there a way to circumvent these issues?
I hope somebody can help me get it to work. Thanks for all your time

Try using Model.LoadOpenSimLibrary("<full-path-to-DLL file>") instead.

Great!

This is working. Thank you very much.
Might it be an idea to add this to the documentation at the top link in the first post?
It works much easier than the loadlibrary().

Keep up the good work.
