Having a matrix A as attached, how to replace all those 1 in A with the values in matrix B, so that i get a new matrix as newA
A(:,:,1) =
0 0 1
0 1 0
0 1 1
A(:,:,2) =
1 0 0
0 0 0
0 0 0
A(:,:,3) =
0 1 0
1 0 1
1 0 0
B = [6 1 5; 2 6 7; 4 6 9];
B =
6 1 5
2 6 7
4 6 9
newA(:,:,1) =
0 0 5
0 6 0
0 6 9
newA(:,:,2) =
6 0 0
0 0 0
0 0 0
newA(:,:,3) =
0 1 0
2 0 7
4 0 0

Ran in:
A= cat(3, [ 0 0 1;
0 1 0;
0 1 1], ...
[1 0 0,
0 0 0;
0 0 0], ...
[0 1 0;
1 0 1;
1 0 0 ]);
B = [6 1 5; 2 6 7; 4 6 9];
A.*B
ans =
ans(:,:,1) = 0 0 5 0 6 0 0 6 9 ans(:,:,2) = 6 0 0 0 0 0 0 0 0 ans(:,:,3) = 0 1 0 2 0 7 4 0 0
