21 ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX trian‐
22 gular matrix, A. RMAX is the overflow for the SINGLE PRECISION arith‐
23 metic
24 ZLAT2C checks that all the entries of A are between -RMAX and RMAX. If
25 not the convertion is aborted and a flag is raised. This is an auxil‐
26 iary routine so there is no argument checking.
27
29 UPLO (input) CHARACTER*1
30 = 'U': A is upper triangular;
31 = 'L': A is lower triangular.
32
33 N (input) INTEGER
34 The number of rows and columns of the matrix A. N >= 0.
35
36 A (input) COMPLEX*16 array, dimension (LDA,N)
37 On entry, the N-by-N triangular coefficient matrix A.
38
39 LDA (input) INTEGER
40 The leading dimension of the array A. LDA >= max(1,N).
41
42 SA (output) COMPLEX array, dimension (LDSA,N)
43 Only the UPLO part of SA is referenced. On exit, if INFO=0,
44 the N-by-N coefficient matrix SA; if INFO>0, the content of the
45 UPLO part of SA is unspecified.
46
47 LDSA (input) INTEGER
48 The leading dimension of the array SA. LDSA >= max(1,M).
49
50 INFO (output) INTEGER
51 = 0: successful exit.
52 = 1: an entry of the matrix A is greater than the SINGLE PRE‐
53 CISION overflow threshold, in this case, the content of the
54 UPLO part of SA in exit is unspecified. ========= End of
