Hi all,
i need to write a code that multiplies the matrix A and the vector B defined below on an element-by-element basis using loops in my code.
A = [1 12 22 10 18; 20 8 13 2 25; 6 19 3 23 14; 4 24 17 15 7; 11 21 16 5 9];
B = [9 7 11 4 23];
thanks in advance for your support

What have you done so far? What specific problems are you having with your code? The algorithm can be found here:

Are you required to use for loops to multiply element by element here or could you make use of standard Matlab functionality such as the code snippet below?
C = A .* B;
One way of doing this using for loops is shown below
C = zeros(size(A)); % preallocate C
for i = 1:size(A,1)
for k = 1:size(A,2)
C(i,k) = A(i,k) * B(k);
end
end
