vector matrix multiplication with increment

for a constant incremental of +1 the out result is to be multiplied and stored in another matrix ex: A=[1 2 3 4 5] and W=4 so the result is to be as OUT=[1*W 2*(W+1) 3*(W+3) 4*(W+4) 5*(W+5)] addition to occur first and then multiplication can u help in this.

Is this homework?

Answer 1

[Sabarinathan Vadivelu]

W = 4;
A = [1 2 3 4 5];
n = numel(A);
for i = 1 : n
    out(i) = [A(i)*(W+i)];
end

Answer 2

[Andrei Bobrov]

out = A.*(W + A)
