Hi All, Would appreciate help cracking this: I have two matrices of row vectors A ( n X d ) and B ( m X d ), n>m . In both matrices the vectors are binary, that is, each component is either 0 or 1. What is an efficient way to find which vectors from B are already in A, for example, A( 2, : ) equals B( 4, : ) etc. For each row in B I need the corresponding row from A. Thanks, Mike. |
