Hi Guillaume,

I understand that you are getting an exception while calling MATLAB function from C# program in R2022a.

You need to add the R2022a COM Reference in your project.

If you have added the COM reference, you need to do a registry clean up, and start from the beginning. The following command will help.

From a shell command prompt:

matlab -unregserver

It is important that you start a MATLAB with administrator rights to successfully execute the following commands:

1. Start the registered MATLAB (R2022a) with admin rights

>> comserver('unregister', 'User', 'all')
>> comserver('unregister')
>> comserver('query')

2. This should return empty

>> regmatlabserver
>> h=actxserver('matlab.application')

Also, confirm that the MATLAB server opened is R2022a and the path is correct.

Make sure to do these on a new started MATLAB and make sure all other instances are closed.

Thank you,
