- CALL LA_SYEVD / LA_HEEVD
( A, W, JOBZ=jobz, UPLO=uplo, INFO=info )
Computes all eigenvalues and, optionally,
eigenvectors of a real symmetric or Hermitian matrix A.
If eigenvectors are desired, it uses a divide and conquer algorithm.
- CALL LA_SPEVD / LA_HPEVD
( AP, W, UPLO=uplo, Z=z, INFO=info )
Computes all the eigenvalues and, optionally, all eigenvectors of a
real symmetric / complex Hermitian matrix A in packed storage.
If eigenvectors are desired, it uses a divide and conquer algorithm.
- CALL LA_SBEVD / LA_HBEVD
( AB, W, UPLO=uplo, Z=z, INFO=info )
Computes all the eigenvalues and, optionally, all
eigenvectors of a real symmetric / complex Hermitian band matrix A.
If eigenvectors are desired, it uses a divide and conquer algorithm.
- CALL LA_STEVD
( D, E, Z=z, INFO=info )
Computes all eigenvalues and, optionally, all eigenvectors of a
real symmetric tridiagonal matrix A.
If eigenvectors are desired, it uses a divide and conquer algorithm.
- CALL LA_GESDD
( A, S, U=u, VT=vt, WW=ww, JOB=job, INFO=job )
Compute the singular values and, optionally, the left and/or right
singular vectors from the singular value decomposition (SVD) of
a real or complex m by n matrix A. If singular vectors are
desired LA_GESDD uses a divide and conquer method.
