Generates the real orthogonal matrix Q of the LQ factorization formed by ?gelqf.
Multiplies a complex matrix by the unitary matrix defined from the factorization formed by ?tzrzf.
Reduces a real symmetric matrix to tridiagonal form with Successive Bandwidth Reduction approach.
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.
This topic describes LAPACK driver routines used for solving linear least squares problems. Table "Driver Routines for Solving LLS Problems" lists all such routines for the FORTRAN 77 interface. The corresponding routine names in the Fortran 95 interface are without the first symbol.
Computes selected eigenvalues and, optionally, eigenvectors of a Hermitian matrix using the Relatively Robust Representations.
Computes all eigenvalues and, optionally, eigenvectors of a real generalized symmetric definite eigenproblem.
