C# MWArray[] as function return type in .NET Assembly

Hi, I implemented a sample function

function [structout, numout, strout] = mydifftypes(str,struct,num)
   structout.num = num;
   structout.str = str;
   structout.struct = struct;
   numout = num + 10;
   strout = [str 'abc'];

and use the deploytool to build the .Net assembly. When I explore the generated assembly source C# code I can see that the function is overloaded:

      public MWArray mydifftypes()
      {
        return mcr.EvaluateFunction("mydifftypes", new MWArray[]{});
      }

      public MWArray mydifftypes(MWArray str)
      {
        return mcr.EvaluateFunction("mydifftypes", str);
      }

      public MWArray mydifftypes(MWArray str, MWArray struct0)
      {
        return mcr.EvaluateFunction("mydifftypes", str, struct0);
      }

      public MWArray mydifftypes(MWArray str, MWArray struct0, MWArray num)
      {
        return mcr.EvaluateFunction("mydifftypes", str, struct0, num);
      }

      public MWArray[] mydifftypes(int numArgsOut)
      {
        return mcr.EvaluateFunction(numArgsOut, "mydifftypes", new MWArray[]{});
      }

      public MWArray[] mydifftypes(int numArgsOut, MWArray str)
      {
        return mcr.EvaluateFunction(numArgsOut, "mydifftypes", str);
      }

      public MWArray[] mydifftypes(int numArgsOut, MWArray str, MWArray struct0)
      {
        return mcr.EvaluateFunction(numArgsOut, "mydifftypes", str, struct0);
      }

      public MWArray[] mydifftypes(int numArgsOut, MWArray str, MWArray struct0, MWArray 
                             num)
      {
        return mcr.EvaluateFunction(numArgsOut, "mydifftypes", str, struct0, num);
      }

      public void mydifftypes(int numArgsOut, ref MWArray[] argsOut, MWArray[] argsIn)
      {
        mcr.EvaluateFunction("mydifftypes", numArgsOut, ref argsOut, argsIn);
      }

I have a few questions: a) How to determine which assembly function to use ? b) I would like to read the assembly function IO parameters names and types. It can be done by using .Net Reflection library. I can simple get the function input parameter names and types however the output parameters are (in the sample case structout, numout, strout) are defined as return type MWArray[]. I would like to know if it is posible to get the output names from this return type somehow ....
