I need to calculate the vector s.t. Ax = 0, for det(A) ~= 0. I've looked at the documentation, octave-forge, etc. but I couldn't find a routine for doing this. Matrix A is pretty big, ie. in the hundreds, but I also have a lot of computer time if the available routine is slow.

Your subject line says A is singular, but your description of the problem says det(A)~=0, which means it is not singular, so which is it? Assuming A is singular, the "null" function will compute a set of basis vectors for the null space of A.
