find the matching coordinates in two matrix

i have matrix containing certain x and y coordinates of images. I have another matrix which have x and y coordinates of images. I want to find which indexes are same by comparing two matrix. Something like:

A = [256 345; 300 356; 400 234; 454 345;100 200] B =[256 345;400 234;] , then the result matrix should be C =[1;0;1;0;0].

I know there is a direct approach like iterating through the matrices and comparing them . I want to know is there any easy and computationally less expensive way of doing this

It works. Thanks!

ismember(A,B,'rows');

is the exact command for anyone wondering
