It is my understanding that using successive over-relaxation can significantly speed convergence of the solution assuming that the coefficient matrix is diagonally dominant. I am curious if people have opinions on the effectiveness of this strategy, and if it is a good one, if anyone has VBA source code to calculate the over-relaxation.

NVIDIA's best practices guide has some things to say about how to measure performance of your code. Since your algorithm is memory-bandwidth-limited (it performs a relatively small number of operations per memory access), the quantity I'd say is more important than the speedup is memory throughput, the number of bytes per second your program. This Python program implements successiveover-relaxation (SOR) method to solve system of linear equations. This program solves system of linear equation having 3 unknowns. You can modify this program to solve higher number of unknowns. Following system of linear equations are used: 3x - y + z = -1 -x + 3y - z = 7 x - y + 3z = -7.
Finally, when I introduce the relaxation parameter w as any value in (1.1, 1.2, 1.3....1,9) the values and the errors shoot up really high and the temperature matrix values shows 'inf'. It seems like the problem occurs when I use the relaxation parameter, but I cannot figure out why it's happening.

Successive Over-Relaxation (SoR) Method in MATLAB. Rajendra Bohara - May 18, 2015. Successive Over-Relaxation Method, also known as SOR method, is popular iterative method of linear algebra to solve linear system of equations. This method is the.
It is my understanding that using successive over-relaxation can significantly speed convergence of the solution assuming that the coefficient matrix is diagonally dominant. I am curious if people have opinions on the effectiveness of this strategy, and if it is a good one, if anyone has VBA source code to calculate the over-relaxation. In the SuccessiveOver-Relaxation (SOR) technique the matrix update after each iteration is done in a different way. In the SOR method, the current matrix summed with alpha times the difference between the two matrices is updated as the current matrix. The process is repeated from alpha=1 to alpha=1.9.
Therefore, the actual solution can only by approximated. Successive over-relaxation (SOR) is a numerical method for solving a linear system of equations - equations that have a linear comination of differential terms. Coefficients in such equation can be functions of the independent variables but not the dependent ones. The finite difference equations at these nodes are solved using a successive point-interative over-relaxation method. fft235.f90 Fast Fourier Transform for the case in which the series length is a multiple of some or all of the integers 2, 3 and 5 (e.g. length = 60 or 240). hartly2d.f90 Hartley 2D Fast Fourier Transform . pzeros.f90 Solve.
Successive-over-relaxation. In numerical linear algebra, the method of successive over-relaxation (SOR) is a variant of the Gauss–Seidel method for solving a linear system of equations, resulting in faster convergence. This project explores the iterative linear solving processes of SOR to analyze a diffusive process.
