cla_gerpvgrw.f - SYNOPSIS
Functions/Subroutines REAL function cla_gerpvgrw (N, NCOLS, A, LDA, AF, LDAF) CLA_GERPVGRW multiplies a square real matrix by a complex matrix. Function/Subroutine Documentation REAL function cla_gerpvgrw (integerN, integerNCOLS, complex, dimension( lda, * )A, integerLDA, complex, dimension( ldaf, * )AF, integerLDAF) CLA_GERPVGRW multiplies a square real matrix by a complex matrix. Purpose: CLA_GERPVGRW computes the reciprocal pivot growth factor norm(A)/norm(U). The "max absolute element" norm is used. If this is much less than 1, the stability of the LU factorization of the (equilibrated) matrix A could be poor. This also means that the solution X, estimated condition numbers, and error bounds could be unreliable. Parameters: N N is INTEGER The number of linear equations, i.e., the order of the matrix A. N >= 0. NCOLS NCOLS is INTEGER The number of columns of the matrix A. NCOLS >= 0. A A is COMPLEX array, dimension (LDA,N) On entry, the N-by-N matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). AF AF is COMPLEX array, dimension (LDAF,N) The factors L and U from the factorization A = P*L*U as computed by CGETRF. LDAF LDAF is INTEGER The leading dimension of the array AF. LDAF >= max(1,N). Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
