null(A)
calculates the singular value decomposition of matrix
A
, such that A = U*S*V'
. The columns of
V
corresponding to singular values equal to zero (within tolerance) form
a set of orthonormal basis vectors for the null space. Different machines and releases of
MATLAB® can produce different singular vectors that are still numerically accurate, so
values calculated using null
may differ.
The rational basis for the null space null(A,"rational")
is obtained
from the reduced row echelon form of A
, as calculated by
rref
.
