SVD and Other things Linear [message #14352]

Hellu,
I am trying to find the non trivial solution for the equation Ax=0 where A
is a known nxm matrix, and x is an unknown 1 x n (or 1xm, I get that
confused) vector. I was using SVD and SVSOL to get the answer, but then I
got to this case, and all I get is x = [0, ...., 0]. Does anyone know if I
can get SVD and SVSOL to find the non-trivial solution, or of any other way
to do this linearly. I have tried to do it nonlinearly, with BROYDEN, but I
keep running into local minimums(maximums), or it not even being able to
converge.

Thank You,
David Borland
