hi
I Need some help with the calling of a matlab compiled DLL (C# under
deploytool). The matlab function is a simple function THAT takes two double and return a
third...
 
i add necessary references to my c# project ...

and its my code :
 

Sum.Class1 a = new Sum.Class1();
           MathWorks.MATLAB.NET.Arrays.MWArray[,] s=new MWArray[1,3];
 
           a.sumab(2, 5, s);
 
             listBox1 .Items.Add(s);
 

the method (sumab) return void and i dont know how can get my output ...
im very amazing
 
if i just write a.sumab(2,5);
it gives me an error:
 
"
... MWMCR::EvaluateFunction error ...
Error using ==> sumab
Too many output arguments..
"
 
please help me friends
tnx a lot

It seems the function in the DLL is at least called. But of course if the function expects 3 Parameters the call 
a.sumab(2,5);
will produce an error. Usually in matlab if you want a return value from a function you call it 
s = a.sumab(2, 5);
since matlab doesnt have reference parameters.
 
I think you should rewrite your Matlab function so that it only excepts 2 parameters and of course returns the result sum.
 
See for example:

But then again why even use Matlab for such a simple task...

Have you tried calling it in C# as i've mentioned? s = a.sumab(2, 5);
