Can you help me to solve this issue, please? I attached a copy of the error message.

Hi Yasser -- it looks like you may be encountering the issue described in this MATLAB Answers post:

Why does MATLAB return an "Error using eval. Undefined function 'workspacefunc' for arguments of type 'struct' error when starting?

Please refer to that post for solutions and next steps.

[Walter Roberson]

Possibly. But notice that they are using a mac but the paths being attempted use \ . Perhaps somehow a Windows startup or pathdef is being used on the Mac

[Yasser Alzamil]

Thank you All, I did set the path for the default and works fine.
