Equation solvers in 'C'

A set of equation solvers in 'C' is presented in this report. The use of these routines in finite element analysis of physical phenomena is very common . Hence it is believed that these modules can be readily implemented in any finite element system being developed.13; The commonly used methods that are chosen are13; 1 . Inversion .13; 2 . Gaussian elimination.13; 3 . Banded solver.13; 4 . Cholesky.
