I know that the rank of a skew-symmetric matrix is even. I just need to find a published proof for it. Could anyone direct me to a source that could help me?

    Another source is [Chapter XV, Section 8](http://books.google.com/books?id=Fge-BwqhqIYC&lpg=PP1&dq=lang%20algebra&pg=PA586#v=onepage&q&f=false) of Lang's _Algebra_.2011-08-15
