说明：  高斯分布期望优化（em）算法matlab实现，流量矩阵模型(Optimization of Gaussian distribution expectations (em) algorithm matlab realized, the flow matrix model)

牛顿-拉夫逊法在数学上是求解非线性代数方程组的有效方法，其要点是把非线性方程求解过程变成反复地对相应的线性方程进行求解的过程。(Newton- Raphson method in mathematics is an effective method for solving nonlinear algebraic equations, the point is that the non-linear equation solving process into the process repeated for the corresponding linear equation solving.)

采用symmetrized split-step method数值求解非线性薛定谔方程(Numerical solution of nonlinear Schrodinger equation by symmetrized split-step method)

说明：  粒子滤波和卡尔曼的比较，希望给大家一些帮助(patical and kalman)

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )

北京到广州铁路路线仿真，可用于完好性分析用(Beijing to Guangzhou railway line simulation can be used to integrity analysis)

信号的抽样和恢复.ppt 信号的抽样和恢复.ppt (信号的抽样和恢复.ppt )

对信号做连续小波变换，不直接调用Matlab的cwt函数(right signals to do continuous wavelet transform, not directly call Matlab cwt function)

1、使用牛顿法求sqrt（2）； 2、用牛顿法求 fx=(x-1)*(exp(x-1)-1)的误差以及误差比； 3、用牛顿法及其他两种方法求 fx=x^4-4*x+x^2的重根 (1, using Newton' s method for the sqrt (2) 2, using Newton' s method for the fx = (x-1)* (exp (x-1)-1) error and error ratio 3, using Newton' s method and the other two method, to calculate fx = x ^ 4-4* x+ x ^ 2 re-root)
