Hello,

I am calling a dll using calllib. Here is the sample code:
calllib('Library_name','tmain',inp_cmd);

the C++ function header is defined as:
__declspec(dllexport) double tmain(char* s)
{
return x;
}

In the above case I am returning one value. I now have to return multiple values so the C++ function is modified as:
__declspec(dllexport) int tmain(char* s, double*x, double*y)
{
x=a+b;
y=c+d;
}

How does MATLAB support call by reference? How will calllib work in this case? Or is there any other way?

Thanks.
