	Full eigendecomposition of a real symmetric matrix.

Detailed Description

Full symmetric eigendecomposition dispatcher.

Backend routing: Backend::lapack -> backends::lapack::eig_sym (LAPACKE_dsyevd, divide-and-conquer) Backend::omp -> backends::omp::eig_sym (cyclic Jacobi, parallel inner loops) everything else -> backends::seq::eig_sym (cyclic Jacobi, sequential)
