可控整流仿真，在simulink下，分析输入侧电压电流波形(Controlled rectifier simulation, analysis of the input side of the voltage and current waveforms in simulink)

Matlab的曲线拟合（CFT）工具箱详细的使用说明，版本Matlab7(Matlab curve fitting toolbox reference Version:Matlab7)

it is the power system in matlab programing

these codes read input image and generate the 2D gabor filters, with changeable scale, orientation, perform the convolution with input image.

本代码分析了全光纤微环谐振器的传输特性，同时分析了谐振器的参数如光纤的直径、微环的半径等，对谐振器的性能如自由光谱范围（FSR）及品质因子Q值的影响。(This code analyze the transmission characteristics of all fiber optic micro-ring resonators and the relation between the resonator parameters, such as the diameter of the optical fiber, the radius of the micor-ring, and the performance of the micro-ring, such as the free spectral range (FSR) and the quality factor Q .)

利用matlab针对图像进行马氏距离计算 ,小波包分析提取振动信号中的特征频率，随机调制信号下的模拟ppm。( Using matlab to calculate the Mahalanobis distance for the image, Wavelet packet analysis to extract vibration signal characteristic frequency, Random ppm modulated analog signal unde.)

This function is a very simple application of FFT2 for an image to simulate the effect of bandpass filter with two cut off frequencies. One can easily modify the programme to do the processes for different images, and even implement highpass and lowpass filter

1.median_filter (功能:使用中值濾波器去除雜訊) 2.mean_filter (功能:使用平均濾波器去除雜訊) 3.fl_stein (功能:使用誤差擴散法,將影像量化和混色) 4.Central_limit (功能:畫圖並證明中央極限定理) (1.median_filter (function: use median filter to remove noise) 2.mean_filter (function: using the average filter to remove noise) 3.fl_stein (function: using the error diffusion method, the image quantification and blending) 4. Central_limit (function: drawing and prove the central limit theorem))
