SYNOPSIS
Functions/Subroutinessubroutine zlag2c (M, N, A, LDA, SA, LDSA, INFO)
ZLAG2C converts a complex double precision matrix to a complex single precision matrix.
Function/Subroutine Documentation
subroutine zlag2c (integer M, integer N, complex*16, dimension( lda, * ) A, integer LDA, complex, dimension( ldsa, * ) SA, integer LDSA, integer INFO)ZLAG2C converts a complex double precision matrix to a complex single precision matrix. 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 conversion is aborted and a flag is raised.
This is an auxiliary routine so there is no argument checking.Parameters: M M is INTEGER
The number of lines of the matrix A. M >= 0.
N N is INTEGER
The number of columns of the matrix A. N >= 0.
A A is COMPLEX*16 array, dimension (LDA,N)
On entry, the M-by-N coefficient matrix A.
LDA LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
SA SA is 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 LDSA is INTEGER
The leading dimension of the array SA. LDSA >= max(1,M).
INFO INFO is INTEGER
= 0: successful exit.
= 1: an entry of the matrix A is greater than the SINGLE
PRECISION overflow threshold, in this case, the content
of SA in exit is unspecified.Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd. Date: December 2016 Definition at line 109 of file zlag2c.f.
