MATLAB: Call methods on MATLAB objects instantiated in a CMEX function

cmexMATLABmethod call

I've got a CMEX function in which I call a MATLAB function to get a MATLAB object like this:
mxArray *plhs[1];
mexCallMATLAB(1, plhs, 0, NULL, "getAnObject");
Now, I want to call a method on this object. In MATLAB, I would have done it like this:
obj = getAnObject;
How can I solve this in a CMEX function?
P.S.: getAnObject itself is a compiled mex file.

  • I found the solution here:
    An alternative way of calling a method on a MATLAB object is this:
    returnedValue = methodName(object,args,...)
    So, transferred to my CMEX file:
    mxArray *plhs[1];
    mexCallMATLAB(1, plhs, 0, NULL, "getAnObject");
    mxArray *params[2];
    params[0] = plhs[0];
    params[1] = mxCreateDoubleScalar(12);
    mexCallMATLAB(0, NULL, 2, params, "aFunction");
    Have a nice day!
