Symmetric Indefinite Factorization Object
- DESCRIPTION:
-
These are objects of class
"lu.Hermitian"
They represent the symmetric indefinite factorization of a
real symmetric or complex Hermitian matrix.
- GENERATION:
-
This class of objects is returned from the lu.Hermitian
function to represent a symmetric indefinite factorization.
- METHODS:
-
The "lu.Hermitian" class of objects has methods for the
following generic functions:
det, expand, facmul, rcond, solve
- STRUCTURE:
-
The following component must be included in a legitimate "lu.Hermitian"
object:
- factors:
-
a matrix in which the triangular and block diagonal factors are stored.
There is an attribute "uplo" associated with this matrix indicating
whether or not the triangular factor is upper or lower triangular.
- pivot:
-
the permutation applied to the original matrix to achieve the
symmetric indefinite factorization.
