*       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
