can you help me insert m x n matrix into M x N matrix with a condition that is without zero.
starting location is (x,y)
M x N =
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
m x n =
0 2 2 0
2 2 2 2
0 2 2 0
(x,y) = (4,3)
M x N =
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 2 2 1 1 1 1

A = [1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1
1 1 1 1 1 1 1 1 1 1];
B = [0 2 2 0
2 2 2 2
0 2 2 0];
row = 3; col = 4;
toinsert = B + ~B .* A(row:row+size(B, 1)-1, col:col+size(B, 2)-1);
A(row:row+size(B, 1)-1, col:col+size(B, 2)-1) = toinsert

What individual calculations?
The code above is completely generic and will work for any size A and B and wherever any zeros are in B.
If it doesn't work for your generic case, then you need to explain a lot better what it is you want.
