- CALL LA_SYEVR / LA_HEEVR
( A, W, JOBZ=jobz, UPLO=uplo, VL=vl, VU=vu, &
IL=il, IU=iu, M=m, ISUPPZ=isuppz, ABSTOL=abstol, INFO=info )
Computes selected eigenvalues and, optionally,
eigenvectors of a real symmetric/complex Hermitian matrix A.
Eigenvalues and eigenvectors can be selected by specifying either a
range of values or a range of indices for the desired eigenvalues.
Uses a Relatively Robust Representation (RRR) algorithm.
- CALL LA_STEVR
( D, E, W, Z=z, VL=vl, VU=vu, IL=il, IU=iu, M=m, &
ISUPPZ=isuppz, ABSTOL=abstol, INFO=info )
Computes selected eigenvalues and, optionally, the corresponding
eigenvectors of a
real symmetric tridiagonal matrix A. Eigenvalues and
eigenvectors can be selected by specifying either a range of values
or a range of indices for the desired eigenvalues. Uses a Relatively Robust
Representation (RRR) algorithm.
