la_lapack::sytrf_aa Interface Reference

SYTRF_AA: computes the factorization of a complex symmetric matrix A using the Aasen's algorithm. The form of the factorization is A = U**T*T*U or A = L*T*L**T where U (or L) is a product of permutation and unit upper (lower) triangular matrices, and T is a complex symmetric tridiagonal matrix. This is the blocked version of the algorithm, calling Level 3 BLAS. More...
