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.
?geequ
Computes row and column scaling factors intended to equilibrate a general matrix and reduce its condition number.
?geequb
Computes row and column scaling factors restricted to a power of radix to equilibrate a general matrix and reduce its condition number.
?gbequ
Computes row and column scaling factors intended to equilibrate a banded matrix and reduce its condition number.
?gbequb
Computes row and column scaling factors restricted to a power of radix to equilibrate a banded matrix and reduce its condition number.
?poequ
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix and reduce its condition number.
?poequb
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix and reduce its condition number.
?ppequ
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive definite matrix in packed storage and reduce its condition number.
?pbequ
Computes row and column scaling factors intended to equilibrate a symmetric (Hermitian) positive-definite band matrix and reduce its condition number.
?syequb
Computes row and column scaling factors intended to equilibrate a symmetric indefinite matrix and reduce its condition number.
?heequb
Computes row and column scaling factors intended to equilibrate a Hermitian indefinite matrix and reduce its condition number.
