Sistem Penyelesaian Sistem Persamaan Linear Menggunakan Kaedah Lelaran


Abstract

          Recently, the numerical analysis in science and engineering become extensively used in the market particularly in solving system of linear equation. Based on the situation,this project as a user-helper focuses on the comparison of several iterative methods in solving system of linear equation. The comparisons of be observed are in terms of the fastest and the most accurate method in problem solving. All the iterative methods proposed are based on matrices. Four methods have been developed and two methods were added for research. The normal methods such as Jacobi,Gauss-Seidel and successive over-relaxation method are applied in this project. Alternatively,preconditioned conjugate gradient method also been developed. The added methods were conjugate gradient and the iterative refinement which enhancing the direct method. This system developmen its based on waterfall methodology.All the above mentioned methods are developed in Java programming language. As for the testing purpose,these methods have to be compared with manual calculation and positive-negative test.
