How to compare values in respective columns using "ismember"

I have a 24x365 matrix (A) and a 4x365 matrix (B). I would like to replace each of the same value from B in same column in A with "1" and the rest to be "0". I have tried using "ismember" but this registers and replaces values from B in A even if they are not in the respectively column. Is there a "simple" way to solve this problem??

Thank you in advanced!!

use ismember on each column separately

for j=1:size(A,2)
    A(:,j) = ismember(A(:,j),B(:,j));
end
