## SYNOPSIS

### Functions/Subroutines

subroutine slag2d (M, N, SA, LDSA, A, LDA, INFO)
SLAG2D converts a single precision matrix to a double precision matrix.

## Function/Subroutine Documentation

### subroutine slag2d (integerM, integerN, real, dimension( ldsa, * )SA, integerLDSA, double precision, dimension( lda, * )A, integerLDA, integerINFO)

SLAG2D converts a single precision matrix to a double precision matrix.

Purpose:

``` SLAG2D converts a SINGLE PRECISION matrix, SA, to a DOUBLE
PRECISION matrix, A.

Note that while it is possible to overflow while converting
from double to single, it is not possible to overflow when
converting from single to double.

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.
```

SA

```          SA is REAL array, dimension (LDSA,N)
On entry, the M-by-N coefficient matrix SA.
```

LDSA

```          LDSA is INTEGER
The leading dimension of the array SA.  LDSA >= max(1,M).
```

A

```          A is DOUBLE PRECISION array, dimension (LDA,N)
On exit, the M-by-N coefficient matrix A.
```

LDA

```          LDA is INTEGER
The leading dimension of the array A.  LDA >= max(1,M).
```

INFO

```          INFO is INTEGER
= 0:  successful exit
```
