SYNOPSIS
Functions/Subroutines subroutine claqge (M, N, A, LDA, R, C, ROWCND, COLCND, AMAX, EQUED) CLAQGE scales a general rectangular matrix, using row and column scaling factors computed by sgeequ. Function/Subroutine Documentation subroutine claqge (integerM, integerN, complex, dimension( lda, * )A, integerLDA, real, dimension( * )R, real, dimension( * )C, realROWCND, realCOLCND, realAMAX, characterEQUED) CLAQGE scales a general rectangular matrix, using row and column scaling factors computed by sgeequ. Purpose: CLAQGE equilibrates a general M by N matrix A using the row and column scaling factors in the vectors R and C. Parameters: M M is INTEGER The number of rows of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= 0. A A is COMPLEX array, dimension (LDA,N) On entry, the M by N matrix A. On exit, the equilibrated matrix. See EQUED for the form of the equilibrated matrix. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(M,1). R R is REAL array, dimension (M) The row scale factors for A. C C is REAL array, dimension (N) The column scale factors for A. ROWCND ROWCND is REAL Ratio of the smallest R(i) to the largest R(i). COLCND COLCND is REAL Ratio of the smallest C(i) to the largest C(i). AMAX AMAX is REAL Absolute value of largest matrix entry. EQUED EQUED is CHARACTER*1 Specifies the form of equilibration that was done. = 'N': No equilibration = 'R': Row equilibration, i.e., A has been premultiplied by diag(R). = 'C': Column equilibration, i.e., A has been postmultiplied by diag(C). = 'B': Both row and column equilibration, i.e., A has been replaced by diag(R) * A * diag(C). Internal Parameters: THRESH is a threshold value used to decide if row or column scaling should be done based on the ratio of the row or column scaling factors. If ROWCND < THRESH, row scaling is done, and if COLCND < THRESH, column scaling is done. LARGE and SMALL are threshold values used to decide if row scaling should be done based on the absolute size of the largest matrix element. If AMAX > LARGE or AMAX < SMALL, row scaling is done.
