step-function

this is introduction to simulink engineering

里面有关于MATLAB的基本使用的方法和定义，初学者可以好好的(There are on the basic use of MATLAB methods and definitions, can be good for beginners)

说明：  matlab实用算法集锦…… 非常多，非常实用…… 各种算法源码及讲解……(Collection of practical algorithm matlab ... ... very large, very useful source and various algorithms ... ... ... ... explain)

给出了通过matlab设计IIR低通滤波器的程序，并通过程序把在DSP中所用到的变量计算出来，很有价值。(Matlab given by IIR low-pass filter design procedures, and procedures used in the DSP in the calculated variables, very valuable.)

GPS基本原理及其matlab实现，包含用户位置求解仿真，GPS卫星动态仿真，C/A码的仿真和调制等(Matlab implementation of the basic principles of GPS, including the location of the user to solve simulation, GPS satellite dynamic simulation, C/A code simulation and modulation)

分析了计算四波混频效率的表到式在考虑非线性相位失配因子和不考虑非线性相位失配因子两种情况下，四波混频效率计算的差别(Analysing the expression of DFWM in the optical fiber under the consideration of nonlinear phase mismatch factor, then comparing the result to the expression which includes only linear phase mismatch factor.)

Optimal Power Flow for HVDC

说明：  使用matlab实现贝叶斯向量自回归模型，可用于经济学中的预测(It can realize Bayesian vector autoregressive model, and it can be used to predict in economics.)

人脸检测的matlab程序，很好用的一个小程序，较新的算法。(Face detection matlab procedures, very good with a small procedure, the newer algorithms.)
