Expanded Symmetric-Indefinite Decomposition Object

DESCRIPTION:

These are objects of class expand.lu.Hermitian They represent the symmetric indefinite decomposition of a real symmetric or complex Hermitian matrix.

GENERATION:

This class of objects is returned from the expand.lu.Hermitian function to represent a symmetric indefinite decomposition. The following components must be included in a legitimate "expand.lu.Hermitian" object:

VALUE:

l
The unit lower triangular/trapezoidal factor.
u
The upper triangular/trapezoidal factor.
permutation
The row permutation applied symmetrically to the original matrix in order to obtain the factorization.
