ZLAG2C(1) LAPACK PROTOTYPE auxiliary routine (version 3.1.2) ZLAG2C(1)NAME
ZLAG2C - converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A
SYNOPSIS
SUBROUTINE ZLAG2C( M, N, A, LDA, SA, LDSA, INFO )
INTEGER INFO, LDA, LDSA, M, N
COMPLEX SA( LDSA, * )
COMPLEX*16 A( LDA, * )
PURPOSE
ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A. RMAX
is the overflow for the SINGLE PRECISION arithmetic
ZLAG2C checks that all the entries of A are between -RMAX and RMAX. If
not the convertion is aborted and a flag is raised. This is an auxil‐
iary routine so there is no argument checking.
ARGUMENTS
M (input) INTEGER
The number of lines of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input) COMPLEX*16 array, dimension (LDA,N)
On entry, the M-by-N coefficient matrix A.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
SA (output) COMPLEX array, dimension (LDSA,N)
On exit, if INFO=0, the M-by-N coefficient matrix SA; if
INFO>0, the content of SA is unspecified.
LDSA (input) INTEGER
The leading dimension of the array SA. LDSA >= max(1,M).
INFO (output) INTEGER
= 0: successful exit.
= 1: an entry of the matrix A is greater than the SINGLE PRE‐
CISION overflow threshold, in this case, the content of SA in
exit is unspecified. ========= End of ZLAG2C
