Hello,

I'm studying MATLAB Coder and I want to convert a function that has MATRICES inputs and a MATRIX output.

Let's say

function A = MULTIPLE(B,C)
columnB = size(B,2);
rowC = size(C,1);
if columnB == rowC
    A = B * C;
else 
    A = 0;
endif
end

The MATLAB Code always asks me the types and sizes of B, C.

If I define them, the coder generates the code.

But I want to get a C function that can accept variable size matrices. Is there any way to do that?
