# 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.
