Purpose:ZLAT2C 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. UPLO
Author:
UPLO is CHARACTER*1 = 'U': A is upper triangular; = 'L': A is lower triangular.N N is INTEGER The number of rows and columns of the matrix A. N >= 0.A A is COMPLEX*16 array, dimension (LDA,N) On entry, the NbyN triangular coefficient matrix A.LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N).SA SA is COMPLEX array, dimension (LDSA,N) Only the UPLO part of SA is referenced. On exit, if INFO=0, the NbyN coefficient matrix SA; if INFO>0, the content of the UPLO part of SA is unspecified.LDSA LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M).INFO INFO is 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.
