说明：  基于高斯赛德尔法的线性方程组解法（可消去系数矩阵病态）。基于牛顿法及改进的牛顿法实现对 非线性方程的求解。(Based Linear Equations high Sisaideer law (coefficient matrix can be eliminated morbid). Realization of nonlinear equations of Newton' s method for solving and improved Newton method is based.)

计算流体力学安德森第七章练习作业，附源程序。。(CFD Anderson Chapter VII practice operations, with source code. .)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )

近似熵和互近似熵的matlab代码，用于脑波分析很有用(Approximate entropy and cross approximate entropy matlab code for brain wave analysis useful)

这是用C++编写的 用高斯方法求解方程的方法 我想对与计算机数学的同学来说 可能会有用(It is written with C++ method for solving equations using Gaussian approach I want to mathematics and computer may be useful for the students)

本程序可模拟ND情况下的傅里叶变换，经过验证无误(This program can simulate the Fourier transform of the ND situation, and after the test, the program is correct )

说明：  在科学与工程计算中，经常遇到求解非线性方程组的问题；非线性方程组在收敛速度及收敛性比线性方程组要差，特别对于非凸的非线性方程组，其求解更是困难。下面简要介绍非线性方程组的三种解法——牛顿法、拟牛顿法、同伦算法，分析三种解法的适用性，并附Matlab原程序。(Scientific and engineering computing, often encounter the problem of solving nonlinear equations speed of convergence of nonlinear equations and linear equations worse than convergence, especially for non-convex nonlinear equations, which is even more difficult to solve . The following briefly describes three solutions to nonlinear equations- Newton method, quasi-Newton method, homotopy method, the applicability of the three solutions, along with Matlab original program.)

这是一个关于高精度阶乘的程序，测试可用！！！(This is a program on the high-precision factorial test available! ! !)

包括脚本文件和函数文件形式，MinkowskiMethod算法 ,抑制载波型差分相位调制。( Including script files and function files in the form, MinkowskiMethod algorithm, Suppressed carrier type differential phase modulation.)
