Masking out unwanted data

Lets say , I have 2 matrix A and B .

A = [1 0 1];

B = [ 2 5 6];

Consider that, for the first element of A ( which is 1) we are getting the first element of B ( which is 2) . and for the second element A ( which is 0 ) we are getting second element in B ( which is 5) and so on.

Now, I want to make the code in such a way that , whenever in the matrix A the code finds its element 1 it mask out element in matrix B.

Example : Matrix A : 1st element is 1 so the code will maskout ( or put zero) in the first element of B which is 2.

Thanks in advance for the help!!!

A = [1 0 1];
B = [2 5 6];

C = B(A ~= 1)

C = 5

% Or:
B(A == 1) = 0

B = 1×3

0 5 0
