number of zeros in a matrix -row by row

onyourmark 
Hi. I have an n x m matrix M some of who's entries are zeros. I want to know
how many zeros there are in each row    -perhaps stored in a 1 x n vector
which lists the number of zeros for each row of M.

Before I had a vector V and I was able to get the number of zeros in V by
doing length(V[ V==0]) but when I try something similar for M, like M[ M==0]
it creates a vector not a matrix and so this does not work. Does anyone have
a solution to this?

Thank you.
