Description Usage Arguments Details Value
Compute eigenvalues and, optionally, eigenvectors of a real symmetric matrix by seraching over ranges of values or ranges of indices.

x |
symmetric, numeric ddmatrix. |
range |
A set of interval endpoints, i.e. a numeric pair. Controls the set of values over which the eigenvalue search occurs. |
range.type |
Controls whether interval |
only.values |
logical. Determines whether only the eigenvalues should be computed, or if the eigenvectors should as well. |
abstol |
The absolute error tolerance for the eigenvalues. |
orfac |
Specifies which eigenvectors should be reorthogonalized. Eigenvectors that correspond to eigenvalues which are within tol=orfac*norm(A)of each other are to be reorthogonalized. |
This new method computes selected eigenvalues and, optionally, eigenvectors of a real symmetric matrix. Eigenvalues and eigenvectors can be selected by specifying either a range of values or a range of indices for the desired eigenvalues.
Returns a distributed matrix.
