Return Value
Type:
SingleAn estimate for the condition
number of the
SingleMatrix.
The condition number of a matrix is defined
as the ratio of its largest to its smallest singular
value. Because the calculation of singular values is
a very expensive operation, an estimate that is
cheaper to calculate is usually preferred.
The condition number gives an indication of
the worst case loss of precision when solving a system
of simultaneous linear equations.
The condition number of a singular matrix
is infinite, which is returned as
PositiveInfinity.
