MATLAB: Element in matrix multiplication to create a new matrix

Question

A and O is 3×1 matrix

B and D is 1×3 matrix

f is a 3×3 matrix

What is wrong with the code below?

i=1:3

j=1:3

T(i,j)=A(i).*B(j).*O(i).*D(j).*f(i,j)

Answer 1

Your code doesn't run because you are using .* which is element wise multiplication instead of standar matrix multiplication. You can do:

for i=1:3
    for j=1:3
        T(i,j)=A(i).*B(j).*O(i).*D(j).*f(i,j)
    end
end

or

T=A*B*O*D*f

depending on the result you are expecting.
