Computes all eigenvalues and eigenvectors of a symmetric or Hermitian matrix reduced to tridiagonal form (QR algorithm).
Reduces a pair of matrices to generalized upper Hessenberg form using orthogonal/unitary transformations.
Uses QR or LQ factorization to solve a overdetermined or underdetermined linear system with full rank matrix.
Computes all eigenvalues and, optionally, eigenvectors of a real symmetric matrix in packed storage.
Computes all eigenvalues and, optionally, eigenvectors of a complex generalized Hermitian positive-definite eigenproblem.
Computes selected eigenvalues and, optionally, eigenvectors of a complex generalized Hermitian positive-definite eigenproblem with banded matrices.
Performs the symmetric rank-1 update of a complex symmetric matrix.
Solves a system of linear equations with a tridiagonal matrix using the LU factorization computed by ?gttrf.
