均匀白噪声、高斯白噪声信号波形，及其自相关函数和频谱密度函数图形(The wave of Even White noise and Gaussian noise,and their Autocorrelation Function and Spectrum Density. )

说明：  小波分析的matlab源代码，是墨西哥帽子的。(wavelet analysis Matlab source code, the Mexican hat.)

this is a matlab code for classify the iris dataset

GUI CREATING IN MATLAB EASY AND FAST

说明：  MATLAB实现的FIR滤波器设计系统。可设计LP、HP、BP、BS四种滤波器，窗型和其他参数也可自由设定(MATLAB realization of FIR filter design system. Can be designed LP, HP, BP, BS in four filters, windows and other parameters can also be set free)

做信号处理的时候经常会用到FFT，而MATLAB自带的FFT只能变换出一列系数，想做成频谱图还要自己加一部分，自己写了一个小程序，输入原始信号和采样率，可以画出标准的幅值谱和功率谱。(Do signal processing is often used when the FFT, and FFT MATLAB own transformation from a coefficient of only wanted to make Canada part of the spectrum but also their own, to write a small program, the input original signal and the sampling rate can be Draw a standard amplitude spectrum and power spectrum.)

grid connected pv systems

模拟混沌与分岔理论，根据沙粒间的相互关系，模拟沙堆崩塌的过程(Analog chaos and bifurcation theory, based on the relationship between sand to simulate the process of sand collapse)

This is a code for periodic impusive noise in ofdm based power line communications. It is implemented in matlab.
