Can not create MATLAB string without MATLAB runtime being initialized.

I create a .NET assembly using a function written in MATLAB. When I want to create a MATLAB String using MWStringArray Class, it generate a exception "Can not create MATLAB string without MATLAB runtime being initialized", but using MWCharArray Class is successful.

Hi Chuguang,

The error indicates that the environment variables for MATLAB are not correctly set. This typically involves ensuring that the MATLAB executable is in your system's PATH.

• Open the Control Panel and go to System > Advanced system settings > Environment Variables.
• Check if the MATLAB installation path is included in the PATH variable.

Ensure that you are using MATLAB functions correctly in your scripts. If you are using this function "matlab.lang.makeValidName", make sure it is supported by MATLAB version.

If the issue still persist, refer to the following MATLAB Answer for license related issue with MATLAB Run time:
