SYNOPSIS
Functions/Subroutines
subroutine 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 (integerM, integerN, complex*16, dimension( lda, * )A,
integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO)
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 convertion 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.
