Given a matrix,
M, find a matrix
N giving a basis for the null space. That is
t(N) %*% M is the zero and
N has the maximum number of linearly independent columns.
- Input matrix. A vector is coerced to a 1-column matrix.
N with the basis for the null space, or an empty vector if the matrix
M is square and of maximal rank.
