MATLAB: Calling an object method where the name of the method is a varible

MATLABobject-oriented

I am trying to call an object method when I have the object instance, the method name, and the argument value(s) as variables. If my object were a COM object, I could use invoke(). Is there something similar to this for user-defined classes? I'm trying to avoid using eval().

You can just do,

object.(methodname)(arg1,arg2,...)

What about overloading subsasgn

classdef myClass < dynamicprops
    methods
        function obj = myClass()
            P = addprop(obj, 'myProp');
        end
    function A = subsasgn(A, S, B)
      switch S.type
        case '.'
          SetProp(A, S.subs, B);
      end
    end
      
          function SetProp(obj, propname, val)
              obj.(propname) = val;
          end
      end
  end

MATLAB: Error using gpuArray/arrayfun (‘MCOS’, ‘CLASSDEF’)

MCOS appears to be the name of the newer object-oriented system that uses classdef to define objects.

Restrictions on the called functions for gpuarray and arrayfun are described at http://www.mathworks.com/help/distcomp/run-element-wise-matlab-code-on-a-gpu.html#bsnx7h8-1

I gather that the problem here is that the function you are passing is defined in a classdef and that just is not permitted.

You might be able to call a function outside of a classdef that referred to a user-defined object, but I do not know if it is possible or not.
