MATLAB: Help for vectorization coding for multiplication and addition matrixs

Question

Hello,

I have two separate codes.

Use of for loops for following codes making them too heavy , so they are taking too long for bigger size matrix's. can anyone please help me to write both in vectorized form.

Thanks

CODE 1—

 Ft= zeros(n,n);
 for row=1:na
     for col =1:nv
        tn(row,col)= st(row,col)*y(row,col);if y(row,col)>0
        tn(row,col) =  tn(row,col)+ff(row,col);
      end
    end
end

Answer 1

Try this:

   Fn = cost.*W+(W>0).*FC;

and

   W = sum(reshape(outp(:,1:n*dr,u),[],n,dr),3);

(I assume u is a scalar index here.)
