Usage
Returns the rank of a matrix. There are two ways to use
the rank function is
y = rank(A,tol)
where tol is the tolerance to use when computing the
rank. The second form is
y = rank(A)
in which case the tolerance tol is chosen as
tol = max(size(A))*max(s)*eps,
where s is the vector of singular values of A. The
rank is computed using the singular value decomposition svd.
