so I have a matrix A=[20 17 18 24, 12 22 27 11, 30 10 15 23, 28 20 14 11]
and a matrix B filled with zeros, of the same size (4x4).
I want to say that if the values of A are bigger than 18, then change the values in matrix B. Also taking into account the position of the elements, so for example the first element A(1,1) is bigger than 18, then B(1,1) will change to 1.
Edit: What if I have 3 matrixes, and the matrix B. So I want to say that if the values in matrix A are bigger than 18, and the values in matrix C are bigger than 10 and the values in matrix D are bigger than 30, then in Matrix B, change from 0 to 1, the element that meet the three conditions.
