## 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 (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.```
