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

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.)
