I have a matrix A like this;
A=[1 2 3 4 5;4 5 6 7 1;3 4 5 9 1; 7 8 9 2 4;1 5 9 5 2];
P is a binary matrix of same size of A; P =
0 1 0 1 0
1 0 0 1 0
0 1 0 0 0
1 1 0 1 1
0 0 0 0 1
I want to replace all 1 of P with the value of A at same index position without using for loop. How can I overcome this problem. Please help me.
