Eigenvalue decomposition for distributed matrices with R-like syntax, with calculations performed by the PBLAS and ScaLAPACK libraries.
# S4 method for ddmatrix eigen(x, symmetric, only.values = FALSE, EISPACK = FALSE)
numeric distributed matrices.
TRUE then the matrix is assumed to be
symmetric and only the lower triangle is used. Otherwise
inspected for symmetry.
TRUE then only the eigenvalues are
returned. Otherwise both eigenvalues and eigenvectors are returned.
eigen() computes the eigenvalues, and eigenvectors if requested. As
