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.)

岩石损伤与断裂力学一直是有限元的弱势领域，必须依赖MATLAB一类的数学软件协助，本书籍提供了基础教程与相关案例。(Rock damage and fracture mechanics have been the weak field of finite element, must rely on MATLAB class of mathematical software to help, this book provides basic tutorials and related cases.)

说明：  包含了悉尼科技大学徐亦达老师的课程课件，有贝叶斯理论、EM算法、卡尔曼滤波、HMM、粒子滤波、概率论相关知识等(The file includes knowledge about EM, HMM, particle filter, kalman filter and so on.)

三次样条插值c++头文件，一些头文件，非常好(Cubic spline interpolation c++ header files, some header files)

说明：  恒模算法的简介，它适用于信道的盲均衡。Matlab程序提供基本的框架，可以修该里面的参数以测试该算法的性能(CMA briefings, which applies to Channel Blind balanced. Matlab to provide a basic framework, it can be done inside of the parameters to test the performance of the algorithm)

几个使用的解线性方程组的程序，包括高斯消去法，高斯列主元法，高斯——赛德尔消去法。简明实用。(Gauss elimaination, Gauss_seidel ellimination)

计算傅里叶变换程序，输入光谱，计算其傅里叶变换极限(Computing the Fourier transform procedure, the input spectra, calculate the Fourier transform limit)

最小二乘法求超定线性方程组得C＋＋模板，还包括矩阵求逆，矩阵乘法等小函数(Overdetermined least-squares method of linear equations have to C templates, also includes matrix inversion, matrix multiplication, such as small function)
