This a matlab program for field distribution of fiber modes.

说明：  用Matlab的GUi实现声音去噪处理，采用小波去燥的方法，对比了不同层分解去燥的绝对误差。(Matlab GUi to achieve sound de-noising processing, wavelet de-drying method, the comparison of different layers of decomposition de-drying absolute error.)

这个是KPCA的matlab工具包，台湾的一个大学开发，能够实现KPCA的基本功能(This is a matlab toolkit KPCA, Taiwan, a university development, to achieve the basic functions of KPCA)

some useful matlab code for data hiding for example psnrcompare wavelet transform arnold transform and ...

基于matlab的误差棒分析，挺不错，和大家交流学习。。(Based matlab error bars, very good, and the exchange of learning. .)

easy code wanted for my project

有限时域差分 FDTD （susan ） 程序(FDTD Using FDTD (susan) program)

1,、设置变量和参量： 　　X(n)为输入向量，或称为训练样本 　　W(n)为权值向量 　　e(n)为偏差 　　d(n)为期望输出 　　y(n)为实际输出 　　η为学习速率 　　n为迭代次数 　　2、初始化，赋给w(0)各一个较小的随机非零值，令n=0 　　3、对于一组输入样本x(n)和对应的期望输出d，计算 　　e(n)=d(n)-X^T(n)W(n) 　　W(n+1)=W(n)+ηX(n)e(n) 　　4、判断是否满足条件，若满足算法结束，若否n增加1，转入第3步继续执行(, set the variables and parameters: X (n) is the input vector, otherwise known as the training sample W (n) for the weight vector e (n) for the deviation d (n) is the desired output y (n) is the actual output η is the learning rate n is the number of iterations)

用matlab控制PID参数，进行调整，可实现仿真，适合初学者(Matlab PID control parameters to be adjusted, enabling simulation, suitable for beginners)

This is a test code to show the spectrum of sine wave.
