Symmetric Eigenvalue Problems: LAPACK Driver
topicdescribes LAPACK driver routines used for solving symmetric eigenvalue problems. See also computational routines that can be called to solve these problems. Table
"Driver Routines for Solving Symmetric Eigenproblems"lists all such driver routines
for the FORTRAN 77 interface.
The corresponding routine names in the Fortran 95 interface are without the first symbol.
Computes all eigenvalues and, optionally, eigenvectors of a real symmetric tridiagonal matrix.
Computes all eigenvalues and (optionally) all eigenvectors of a real symmetric tridiagonal matrix using divide and conquer algorithm.
