Interfacing matlab with opensim

[AYUSH RAI]

Hi,
I am trying to interface opensim4.0 using matlab and after running "org.opensim.modeling.opensimCommon.GetVersion()" in command prompt I am getting this:


Failed to load one or more dynamic libraries for OpenSim.
java.lang.UnsatisfiedLinkError: C:\OpenSim 4.0\bin\osimJavaJNI.dll: The specified procedure could not be found
Make sure OpenSim's bin directory is on your PATH.
See https://simtk-confluence.stanford.edu/d ... ith+Matlab
Java exception occurred:
java.lang.UnsatisfiedLinkError: org.opensim.modeling.opensimCommonJNI.GetVersion()Ljava/lang/String;

at org.opensim.modeling.opensimCommonJNI.GetVersion(Native Method)

at org.opensim.modeling.opensimCommon.GetVersion(opensimCommon.java:25)

Can anyone explaing in simple steps how to resove this? P.S. I am not very much of a computer science expert.

There's a "Troubleshooting" section at the bottom of the "Scripting with Matlab" page in the Confluence documentation (linked in the error message; https://simtk-confluence.stanford.edu:8 ... ith+Matlab). Please see the third and fourth items in the list. I can't tell which OS you're using, so I'll assume you're using Windows 10. To edit your Windows PATH environment variable, open the Start menu and type "Edit the system environment variables". In the "System Properties" window that appears, click the "Environment Variables..." button. Under "System variables", select the "Path" variable and click "Edit...". If it isn't there already, add "C:\OpenSim 4.0\bin" to the list (your installation directory may differ) and remove any entries from previous OpenSim versions. If this directory was already in the list, please follow the instructions on the "Scripting with Matlab" page for installing Microsoft Visual C++ Redistributable Package.

Thank you very much. That worked
