6 ZLAG2C - converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A

9 SUBROUTINE ZLAG2C( M, N, A, LDA, SA, LDSA, INFO )
10
11 INTEGER INFO, LDA, LDSA, M, N
12
13 COMPLEX SA( LDSA, * )
14
15 COMPLEX*16 A( LDA, * )

18 ZLAG2C converts a COMPLEX*16 matrix, SA, to a COMPLEX matrix, A. RMAX
19 is the overflow for the SINGLE PRECISION arithmetic
20 ZLAG2C checks that all the entries of A are between -RMAX and RMAX. If
21 not the convertion is aborted and a flag is raised. This is an auxil‐
22 iary routine so there is no argument checking.
23
25 M (input) INTEGER
26 The number of lines of the matrix A. M >= 0.
27
28 N (input) INTEGER
29 The number of columns of the matrix A. N >= 0.
30
31 A (input) COMPLEX*16 array, dimension (LDA,N)
32 On entry, the M-by-N coefficient matrix A.
33
34 LDA (input) INTEGER
35 The leading dimension of the array A. LDA >= max(1,M).
36
37 SA (output) COMPLEX array, dimension (LDSA,N)
38 On exit, if INFO=0, the M-by-N coefficient matrix SA; if
39 INFO>0, the content of SA is unspecified.
40
41 LDSA (input) INTEGER
42 The leading dimension of the array SA. LDSA >= max(1,M).
43
44 INFO (output) INTEGER
45 = 0: successful exit.
46 = 1: an entry of the matrix A is greater than the SINGLE PRE‐
47 CISION overflow threshold, in this case, the content of SA in
48 exit is unspecified. ========= End of ZLAG2C
