Hi:
was wondering if somebody can help me with this I came across in a paper.
$e_k$ is a vector of $k$ $1's. M is a matrix of size n \times k. The author talks about projecting $M$ onto the null space of $e_k$. This is what confuses me. Which $x$ apart from the 0-vector solves e_kx=0.
any help will be appreciated.
