Purpose:

 CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 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:

[in]	M	M is INTEGER The number of lines of the matrix A. M >= 0.
[in]	N	N is INTEGER The number of columns of the matrix A. N >= 0.
[in]	SA	SA is COMPLEX array, dimension (LDSA,N) On entry, the M-by-N coefficient matrix SA.
[in]	LDSA	LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M).
[out]	A	A is COMPLEX*16 array, dimension (LDA,N) On exit, the M-by-N coefficient matrix A.
[in]	LDA	LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
[out]	INFO	INFO is INTEGER = 0: successful exit
