Block Thomas Algorithm: A generalized tridiagonal solver for block matrices, suitable for 2D discretized problems. SOR (Successive Over-Relaxation) Method: An iterative method for faster convergence ...

This program compares the Thomas Algorithm and the Gauss-Jordan Method for solving tridiagonal systems of linear equations. It evaluates their performance by measuring CPU time and residual errors ...

By using this idea an accelerated C ++ + + code is devised, for solving (quasi-) block-tridiagonal linear algebraic equation systems by means of an extended Thomas algorithm.
