Description

Arguments
Details
Value
Description
Eigenvalue decomposition.
Usage
1
Arguments
x
The input matrix.
only.values
Should only the eigenvalues be returned, or should the eigenvectors
also be returned?
descending
Should the values/vectors be returned in descending order,
or ascending order? By default, LAPACK returns them in ascending
order, so putting them in descending order (R's default in eigen())
has a performance cost.
Details
Runtime performance for a SymMat (symmetric packed matrix) will be
MUCH slower than when using full (non-packed) storage.
Value
A matrix-like object of the same type as the input.
