zhptrs solves a system of linear equations A*X = B with a complex
Hermitian matrix A stored in packed format using the factorization
A = U*D*U**H or A = L*D*L**H computed by CHPTRF.
-
* UPLO (input)
-
Specifies whether the details of the factorization are stored
as an upper or lower triangular matrix.
-
* N (input)
-
The order of the matrix A. N >= 0.
