Webb1 nov. 2002 · The Gauss algorithm is simplified to be shown in Fig. 3. After the triangularisation of the matrix A by the algorithm (A GR), we compute the solution X by solving a triangular system. The algorithm (A GR) will be clear, easy to program, favourable to parallelism and convenient for the resolution of many linear systems of . Conclusion
