Code for elements in equation to create a matrix

D is a 1x3 matrix

f is a 3x3 matrix

I want to create a matrix of A by the following equation:

for j=1:3

for i=1:3

A(i)=(sum(D(j).*f(i,j)))^-1;

end

end

But it turns out that the answer is wrong

What should be the correct code of this equation?

Answer 1

[Mischa Kim]

Lo, no need to use loops:

 A = 1./(f*D)

Make sure that D is a column vector.

[lo]

how about if I want to get this equation

using the answer of A?

O is a 1x3 or 3x1 matrix

Answer 2

[Muhammad Tabish Bilal]

for counter1= 1: 13 % counter for the rows of intended matrices
    for counter2= 1 : 13 % counter for coloumns of intended matrices
      SMO(counter1,counter2)  = counter1+counter2; % here you may use the equation you want to drive a matrices from but keep in mind it should be a column matrices using the same counter of inner loop
    end
end
