37 *> SLAG2D converts a SINGLE PRECISION matrix, SA, to a DOUBLE
38 *> PRECISION matrix, A.
40 *> Note that while it is possible to overflow while converting
41 *> from double to single, it is not possible to overflow when
42 *> converting from single to double.
44 *> This is an auxiliary routine so there is no argument checking.
53 *> The number of lines of the matrix A. M >= 0.
59 *> The number of columns of the matrix A. N >= 0.
64 *> SA is REAL array, dimension (LDSA,N)
65 *> On entry, the M-by-N coefficient matrix SA.
71 *> The leading dimension of the array SA. LDSA >= max(1,M).
76 *> A is DOUBLE PRECISION array, dimension (LDA,N)
77 *> On exit, the M-by-N coefficient matrix A.
83 *> The leading dimension of the array A. LDA >= max(1,M).
