NAMEZLAT2C - converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX triangular matrix, A
SYNOPSISSUBROUTINE ZLAT2C( UPLO, N, A, LDA, SA, LDSA, INFO ) CHARACTER UPLO INTEGER INFO, LDA, LDSA, N COMPLEX SA( LDSA, * ) COMPLEX*16 A( LDA, * )
PURPOSEZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX triangular matrix, A. RMAX is the overflow for the SINGLE PRECISION arithmetic
ZLAT2C checks that all the entries of A are between -RMAX and RMAX. If not the convertion is aborted and a flag is raised. This is an auxiliary routine so there is no argument checking.
ARGUMENTSUPLO (input) CHARACTER*1 = 'U': A is upper triangular;
= 'L': A is lower triangular. N (input) INTEGER The number of rows and columns of the matrix A. N >= 0. A (input) COMPLEX*16 array, dimension (LDA,N) On entry, the N-by-N triangular coefficient matrix A. LDA (input) INTEGER The leading dimension of the array A. LDA >= max(1,N). SA (output) COMPLEX array, dimension (LDSA,N) Only the UPLO part of SA is referenced. On exit, if INFO=0, the N-by-N coefficient matrix SA; if INFO>0, the content of the UPLO part of SA is unspecified. LDSA (input) INTEGER The leading dimension of the array SA. LDSA >= max(1,M). INFO (output) INTEGER = 0: successful exit.
= 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold, in this case, the content of the UPLO part of SA in exit is unspecified. ========= .. Local Scalars .. .. .. Intrinsic Functions .. .. .. External Functions .. .. .. Executable Statements .. End of ZLAT2C 0
