# Matlab Simulation using Webots!

I am trying to run this youbot ( sample world) from webots, where the controller is implemented in MATLAB, on running the code it pops out the following error seen in the picture attached. I have also however installed the Support for MinGW-w64 C/C++ Compiler, though it still shows the same error. Could someone help a bit? The error is as follows:

Warning: Name is nonexistent or not a directory: C:\Program Files\Webots\lib\matlab

Waiting up to 5 seconds for C:\Users\asus\AppData\Local\Temp\webots_matlab_lock to be deleted by another MATLAB instance.

• I added the error! I hope it is fine now? – Aditya Sharma Apr 23 at 16:56
• I voted to close this question because there are no details of what OP has done to try to solve the problem, like installing the Webots library or installing a MEX compiler. – Chuck Sep 23 at 15:47
