A Generalized Symbolic Thomas Algorithm
Author(s) Moawwad El-Mikkawy*
ABSTRACT
The current paper is mainly devoted to construct a generalized symbolic Thomas algorithm that will never fail. Two new efficient and reliable computational algorithms are given. The algorithms are suited for implementation using computer algebra systems (CAS) such as Mathematica, Macsyma and Maple. Some illustrative examples are given.
