Expanded LU Decomposition Object

DESCRIPTION:

These are objects of class expand.lu.Matrix They represent the LU decomposition of a matrix.

GENERATION:

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

VALUE:

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