ddmatrix-eigen: eigen

Description

Eigenvalue decomposition for distributed matrices with R-like syntax, with calculations performed by the PBLAS and ScaLAPACK libraries.

Usage

# S4 method for ddmatrix
eigen(x, symmetric, only.values = FALSE,
  EISPACK = FALSE)

Arguments

x

numeric distributed matrices.

symmetric

logical, if TRUE then the matrix is assumed to be symmetric and only the lower triangle is used. Otherwise x is inspected for symmetry.

only.values

logical, if TRUE then only the eigenvalues are returned. Otherwise both eigenvalues and eigenvectors are returned.

EISPACK

Ignored.

Value

eigen() computes the eigenvalues, and eigenvectors if requested. As
