NAME¶

CLA_PORCOND_X - CLA_PORCOND_X Compute the infinity norm condition number of op(A) * diag(X) where X is a COMPLEX vector

SYNOPSIS¶

REAL FUNCTION

CLA_PORCOND_X( UPLO, N, A, LDA, AF, LDAF, X, INFO, WORK, RWORK )

IMPLICIT NONE CHARACTER UPLO INTEGER N, LDA, LDAF, INFO COMPLEX A( LDA, * ), AF( LDAF, * ), WORK( * ), X( * ) REAL RWORK( * )

PURPOSE¶

CLA_PORCOND_X Computes the infinity norm condition number of
op(A) * diag(X) where X is a COMPLEX vector.
WORK is a COMPLEX workspace of size 2*N, and
RWORK is a REAL workspace of size 3*N.
