* SUBROUTINE SLAG2D( M, N, SA, LDSA, A, LDA, INFO )
*
* .. Scalar Arguments ..
* INTEGER INFO, LDA, LDSA, M, N
* ..
* .. Array Arguments ..
* REAL SA( LDSA, * )

*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> 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.
*> \endverbatim
*
* Arguments:
* ==========
*
*> \param[in] M
*> \verbatim
*> M is INTEGER
*> The number of lines of the matrix A. M >= 0.
*> \endverbatim
*>
*> \param[in] N
*> \verbatim
*> N is INTEGER
*> The number of columns of the matrix A. N >= 0.
*> \endverbatim
*>
*> \param[in] SA
*> \verbatim
*> SA is REAL array, dimension (LDSA,N)
*> On entry, the M-by-N coefficient matrix SA.
*> \endverbatim
*>
*> \param[in] LDSA
*> \verbatim
*> LDSA is INTEGER
*> The leading dimension of the array SA. LDSA >= max(1,M).
*> \endverbatim
*>
*> \param[out] A
*> \verbatim
*> A is DOUBLE PRECISION array, dimension (LDA,N)
*> On exit, the M-by-N coefficient matrix A.
*> \endverbatim
*>
*> \param[in] LDA
*> \verbatim
*> LDA is INTEGER
*> The leading dimension of the array A. LDA >= max(1,M).
*> \endverbatim
*>
*> \param[out] INFO
*> \verbatim
*> INFO is INTEGER
*> = 0: successful exit
