subroutine zpotrs (UPLO, N, NRHS, A, LDA, B, LDB, INFO)
subroutine zpotrs (characterUPLO, integerN, integerNRHS, complex*16, dimension( lda, * )A,
integerLDA, complex*16, dimension( ldb, * )B, integerLDB, integerINFO)
ZPOTRS solves a system of linear equations A*X = B with a Hermitian
positive definite matrix A using the Cholesky factorization
A = U**H * U or A = L * L**H computed by ZPOTRF.
UPLO is CHARACTER*1
= 'U': Upper triangle of A is stored;
= 'L': Lower triangle of A is stored.
N is INTEGER
The order of the matrix A. N >= 0.
NRHS is INTEGER
The number of right hand sides, i.e., the number of columns
of the matrix B. NRHS >= 0.
A is COMPLEX*16 array, dimension (LDA,N)
The triangular factor U or L from the Cholesky factorization
A = U**H * U or A = L * L**H, as computed by ZPOTRF.
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,N).
B is COMPLEX*16 array, dimension (LDB,NRHS)
On entry, the right hand side matrix B.
On exit, the solution matrix X.
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO is INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
