public interface hetrs_3
HETRS_3 solves a system of linear equations A * X = B with a complex
Hermitian matrix A using the factorization computed
by CHETRF_RK or CHETRF_BK:
A = PUD(UH)(PT) or A = PLD*(LH)(PT),
where U (or L) is unit upper (or lower) triangular matrix,
UH (or LH) is the conjugate of U (or L), P is a permutation
matrix, P*T is the transpose of P, and D is Hermitian and block
diagonal with 1-by-1 and 2-by-2 diagonal blocks.
This algorithm is using Level 3 BLAS.
