Ker A \subset Ker B

  1. Feb 22, 2012 #1
    Hello,

    I am trying to find a reference for the following results :

    Let A and B be two matrices :
    Ker A \subset Ker B if and only if there exists M such that B= MA

    I already have a proof for this statement, but it looks like a classical algebraic result, so I'm looking for a reference to add in my paper, like a book or a paper..

    Thanks in advance for any suggestions..

    I'm watching the knicks right now and admit i don't see it quite completely in my head, but this looks like a homework level question. so a reference would be in a beginning textbook.
