MPI jacobi iterator (c++ version)

Original link Two-hour introduction to MPI and parallel computing (5): Peer-to-peer mode (parallel computing to achieve Jacobi iteration) – Zhihu Because the original text only has Fortran, and the code in the comment link does not consider that C++ is the row major storage format, the corresponding C++ code is provided here. The corresponding 2D […]

Solve linear equations using Python to implement iterative methods (Jacobi iteration, Gauss-Seidel iteration, relaxation iteration)

1. Jacobi iteration The Jacobi iteration method is an iterative algorithm for solving systems of linear equations. It belongs to the direct iteration method among the iterative methods, and it approximates the solution of the linear equation system by continuously updating the solution vector iteratively. The basic concepts of Jacobi iteration method are as follows: […]

Remember the process of jacob + freemarker exporting a word document 1. Create a freemarker template file 2. Use of Freemarker 3. Jacob uses 3.1, found the problem 3.2. Check the cause 3.3, solve the problem using jacob 3.3.1. Preliminary preparation step 1 step 2 step 3 Things that jacob needs to pay attention to: […]

music algorithm and parallel Jacobian (Jacobian) decomposition

This article is transferred from Zhihu “Shan Qiongxin” article “1 Spatial Spectrum Estimation and Direction Finding”, the original link: https://zhuanlan.zhihu.com/p/160838685 Feeling that there are few direction finding documents and actual simulations, I will summarize the DOA estimation problem based on MUSIC. (Writing the formula is too strenuous, just take a screenshot~) Spatial Spectrum Estimation Direction […]
