label a matrix according to another label matrix

1 view (last 30 days)
I have a label matrix A
A=[1 1 1 1; 1 1 2 3; 3 2 1 4]
I have another boolean matrix B, each element labels each label in matrix A to be true or false
B=[0 0 1 1] % in A, label 1 and label 2 are false, label 3 and label 4 are true
How can I change matrix A according to B, result would look like:
A=[0 0 0 0; 0 0 0 1; 1 0 0 1]
