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.
