Return Value
An estimate for the condition number of the Matrix.Remarks
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.
Use the GetConditionNumber()
method to get the exact condition number.
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.
