SYNOPSIS
Functions/Subroutines
subroutine zlat2c (UPLO, N, A, LDA, SA, LDSA, INFO)
ZLAT2C converts a double complex triangular matrix to a complex triangular matrix.
Function/Subroutine Documentation
subroutine zlat2c (characterUPLO, integerN, complex*16, dimension( lda, * )A, integerLDA,
complex, dimension( ldsa, * )SA, integerLDSA, integerINFO)
ZLAT2C converts a double complex triangular matrix to a complex triangular matrix.
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.
Parameters:
UPLO
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.
