when i execute Matlab Sim command from C#.net using MLApp.MLAppClass , error is coming. But same can be run directly from Matlab.

Error text is as follows. "Stateflow License could not be checked out. Defaulting to a demonstrative version of stateflow. You can load and simulate stateflow demo digrams only. Saving Simulink models containing stateflow block is prohibited."

But Sim command on the same model can be executed successfully directly from Matlab.

Do you have multiple versions of MATLAB installed? Perhaps your call from C#.NET is invoking a version of MATLAB that does not have a Stateflow license? If you have only one installation of MATLAB, run the command "ver" and see if Stateflow is listed.
