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..
