pub trait ReciprocalConditionNumInto<A: Scalar> {
    fn rcond_into(self) -> Result<A::Real>;
}
Expand description

An interface for estimating the reciprocal condition number of matrices.

Required Methods

Estimates the reciprocal of the condition number of the matrix in 1-norm.

This method uses the LAPACK *gecon routines, which estimate self.inv().opnorm_one() and then compute rcond = 1. / (self.opnorm_one() * self.inv().opnorm_one()).

  • If rcond is near 0., the matrix is badly conditioned.
  • If rcond is near 1., the matrix is well conditioned.
