Calling a user function from Python gives error

Hi,

I have user Matlab function. It is written by someone else. There are multiple functions in that file but the first function that has the same name as the .m file itsel is the one that I try to call. It gets 4 arguments (string, string, string, boolean).

Usually in Matlab I call it like this: function('string', 'string, true)

When trying in Python I use following code.

The error I get is following:

Error using resimPrepareNewVersion
Too many output arguments.

Too many output arguments.

I don't understand the error. I already give the same arguments as in Matlab. Even when I give it 3, 2, or no arguments I get the same error. When Matlab loads this functions are loaded automatically so I don't need to add path but I did it any way. However, I tried without giving any path. Code generation and starting Matlab goes without any problem. In Matlab this function loads some other files and opens a info dialog it it means anything.
