Return Value

The condition number of a matrix is defined as the ratio of its largest to its smallest singular value. The condition number of a permutation matrix is always 1.

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.
