[Gsll-devel] Wrong dimension is assumed when an optional parameter is not specified in sv-solve

[Evgeniy Zhemchugov]

SV-decomposition of matrix A (m x n) produces matrices U (m x n) and V
(n x n) and a vector s representing the diagonal matrix S (n x n) so
that A = U S V'. The solution of the equation Ax = b, x, is of
dimension n that is equal to (dim0 V) rather than (dim0 U) as is
written in SV-solve for its optional parameter. Hence the patch.
Obviously, bug appears only for non-rectanular A, so it passed the
tests.
