Error using Matlab Plot

Hello,

I am always getting an Error when I am trying to use either the Matlab Plot or Matlab Snippet node.

The console says

ERROR Matlab Plot 3:109 Execute failed: Could not launch MATLAB. This is likely caused by MATLAB not being in a known location or on a known path. MATLAB's location can be explicitly provided by using matlabcontrol.MatlabProxyFactoryOptions.Builder's setMatlabLocation(...) method.

OS: Windows 7

 

Can you help me?

Thank you.
