MATLAB is one of several tools for working with mathematics. As an experienced programmer, I was skeptical at rst. Why should I learn another programming language when I could do the work in C/C++? The answer was simple: working with MATLAB is easier! Yes, there are some instances when one would want to use another language. A compiled program, such as one written in C++, will run faster than an interpreted MATLAB program (where each line is translated by the computer when the program is run). For hardware design, one might want to write a program in Verilog or VHDL, so that the program can be converted to a circuit.

邻域平均法滤波 原图像画面清晰，添加勒椒盐噪声后图像上产生勒明显的黑色斑点（噪声），用不同模板的平滑滤波处理后图像上的噪声消失，但是图像变得模糊，并且，使用的模板越大，对图像的去噪效果越好，同时图像也变得越模糊。 (Neighborhood averaging filter clear picture of the original image, add the Le Salt and pepper noise generated after the image Roming noticeable black spots (noise), smoothing with different template processed image noise disappear, but the images become blurred, and the use of template bigger the better the image de-noising the same time, the image becomes more blurred.)

模拟退化算法在C环境下的实现，以及在Matlab中对其进行调用。(Simulation of the degradation of algorithm in C environment to achieve, as well as in Matlab in their call.)

general training of neural network

matlab 经典例程里的各种绘图函数，对迅速掌握matlab相关绘图工具很有帮助(the Matlab classic routines in a variety of drawing functions, quickly grasp the matlab drawing tools helpful)

Butterworth Bandpass Filter

应用PCA进行特征提取和降维，可以应用于数据挖掘，机器学习，人脸识别上！(Application of PCA for feature extraction and dimensionality reduction can be applied to data mining, machine learning, face recognition on!)

运用P-Q分解法来进行潮流计算，数据调用需要用到excel(PQ decomposition method using flow calculation, data upload need to use excel)

这是一个简单的语音基音检测方法，通过对语音信号进行滤波、分帧、求自相关函数，可得到浊音的基音周期，从而实现基频检测。(This is a simple voice pitch detection, voice signals by filtering, sub-frame, find the autocorrelation function, voiced the pitch period available to achieve the fundamental frequency testing.)

说明：  混沌时间序列 c-c法求时间延迟的matlab程序，内含语句注解，不需要下载混沌工具箱，可直接使用，超方便！！！ (Method of chaotic time series time delay cc matlab program, containing statement notes, do not need to download the chaotic toolbox can be used directly, super convenient! ! !)
