Fortran

English

Computes the inverse of a triangular matrix using packed storage.

English

Routines described in this section are used to compute scaling factors needed to equilibrate a matrix. Note that these routines do not actually scale the matrices.

English

Computes row and column scaling factors intended to equilibrate a general matrix and reduce its condition number.

English

Computes row and column scaling factors restricted to a power of radix to equilibrate a general matrix and reduce its condition number.

English

Computes row and column scaling factors intended to equilibrate a banded matrix and reduce its condition number.

English

Computes row and column scaling factors restricted to a power of radix to equilibrate a banded matrix and reduce its condition number.

English

Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix and reduce its condition number.

English

Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix and reduce its condition number.

English

Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix in packed storage and reduce its condition number.

English

Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive-definite band matrix and reduce its condition number.
