How to compare two matrix?

I am having two matrix of sizes 7*7 and 7*1. Now, i need to compare both matrix and entries in one matrix varies based on another matrix. For example, element in fourth row first column of matrix A is 1 and element in first row of matrix B is, so, expected output at matrix C is element 1 in fourth row of first column, whereas remaining terms are 0. Similarly, element in first row of fourth column is 1 in matrix A and fourth entry of matrix B is 0, so output matrix C has 0 element in first row of fourth column. Thank you in advance.

Example:

A=[0 0 0 1 0 0 0

0 1 0 0 0 0 0

0 0 0 0 1 0 0

1 0 0 0 0 0 0

0 0 0 0 0 1 0

0 0 1 0 0 0 0

0 0 0 0 0 0 1]

B=[1; 1; 0; 0; 1; 0; 1]

Expected output:

C=[0 0 0 0 0 0 0

0 1 0 0 0 0 0

0 0 0 0 1 0 0

1 0 0 0 0 0 0

0 0 0 0 0 0 0

0 0 0 0 0 0 0

0 0 0 0 0 0 1]

One way:

A=[0    0    0    1    0    0    0
   0    1    0    0    0    0    0
   0    0    0    0    1    0    0
   1    0    0    0    0    0    0
   0    0    0    0    0    1    0
   0    0    1    0    0    0    0
   0    0    0    0    0    0    1];
B=[1; 1; 0; 0; 1; 0; 1];

C = zeros(size(A));
idx = logical(B);
C(:,idx) = A(:,idx)

C = 7×7

0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1
