1 SUBROUTINE CLAG2Z( M, N, SA, LDSA, A, LDA, INFO)
3 * -- LAPACK PROTOTYPE auxilary routine (version 3.1.1) --
4 * Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..
8 * .. WARNING: PROTOTYPE ..
9 * This is an LAPACK PROTOTYPE routine which means that the
10 * interface of this routine is likely to be changed in the future
11 * based on community feedback.
14 * .. Scalar Arguments ..
15 INTEGER INFO,LDA,LDSA,M,N
17 * .. Array Arguments ..
25 * CLAG2Z converts a COMPLEX SINGLE PRECISION matrix, SA, to a COMPLEX
26 * DOUBLE PRECISION matrix, A.
28 * Note that while it is possible to overflow while converting
29 * from double to single, it is not possible to overflow when
30 * converting from single to double.
32 * This is a helper routine so there is no argument checking.
38 * The number of lines of the matrix A. M >= 0.
41 * The number of columns of the matrix A. N >= 0.
43 * SA (output) REAL array, dimension (LDSA,N)
44 * On exit, the M-by-N coefficient matrix SA.
46 * LDSA (input) INTEGER
47 * The leading dimension of the array SA. LDSA >= max(1,M).
49 * A (input) DOUBLE PRECISION array, dimension (LDA,N)
50 * On entry, the M-by-N coefficient matrix A.
53 * The leading dimension of the array A. LDA >= max(1,M).
55 * INFO (output) INTEGER
56 * = 0: successful exit
