用BP进行非线性动态系统辨识 (BP carried out using nonlinear dynamic system identification)

说明：  《MATLAB7.x与C/C++混合编程》配套的源程序 6.5.2节代码 vc.net通过扩展MFC动态链接库创建MEX程序(&quot MATLAB7.x and C/C++ mixed programming,&quot supporting the source code vc.net 6.5.2 MFC dynamic link library by extending the program to create MEX)

This does convolution of two sequences in stepwise manner according to normal understanding. sigfold.m:-fips signal 1..and changes n accordingly. sigshift.m:-shifts flipped signal from left to right to cover all overlapping sigmulti.m:-multiplies two signals at each instant of overlapping convolution.m:-it finally calculates the sum of the product

this document present how we use butterworth ,chybi1,chiby2 and recursif fiter using matlab

说明：  逐条路由算法的matalb实例仿真，绝对跑得通请大家放心(hop by hop routing)

主要是利用归一化的方法进行位场边界识别，利用导数与周围最大值的比值来进行。(Mainly using the method of normalized potential field boundary identification, the use of derivative and the ratio of maximum to be around.)

利用matlab实现几何矩部不变量的简单算法。(The geometric moments of the invariant of the simple algorithm.)

基于matlab语言的抗震工程分析，里面很多代码值得学习。(Matlab language-based seismic engineering analysis, which a lot of code is worth studying.)

pca进行人脸识别的原理和代码，特征脸方法，图像重建(PCA for face recognition principle and code, Eigenfaces method, image reconstruction)

基于遗传算法和非线性规划的函数寻优算法，用遗传算法和非线性规划的函数寻优算法寻找最优值,其中包括三个线性例子和三个非线性例子。(Based on genetic algorithms and nonlinear programming function optimization algorithm, genetic algorithm and nonlinear programming function optimization algorithm to find the optimal value, which includes three examples and three linear nonlinear examples.)
