频谱方差在语音信号端点检测中的应用，matlab程序，实用。(spectrum of the voice signal variance endpoint detection, the application procedures Matlab and practical.)

是给一个有限长序列补零（可以在前面或后面补零），用Matlab画图比较原序列，前补零序列以及后补零序列(very good)

说明：  中文版的matlab文档，适合那些和我一样英语不好的同学(Chinese version of matlab files, suitable for those who, like me, English not good students)

随机权重法改进粒子群优化算法， 更换目标函数后使用(Random weight method to improve particle swarm optimization algorithm, the objective function after the use of replacement)

Design Embedded system

基于matlab的功率谱分析以及短时傅立叶变换(Matlab based on the power spectrum analysis as well as the short-time Fourier transform)

this code is to do OCR using NN

matlab code for image to pixels conversion and vice verse

这个程序是拿来计算像差的，输入相关变量，运行就能计算出像差的值(This program is used to calculate the aberrations, enter the relevant variables, running can calculate the value of the aberration)

说明：  利用MATLAB强大的图形处理功能，符号运算功能和数值计算功能，实现连续时间非周期信号频域分析的仿真波形； 1、用MATLAB实现典型非周期信号的频域分析； 2、用MATLAB实现信号的幅度调制； 3、用MATLAB实现信号傅立叶变换性质的仿真波形； (The use of MATLAB powerful graphics processing capabilities, symbolic computing and numerical computing capabilities to achieve continuous-time non-periodic signal frequency domain analysis of the simulation waveform 1, using MATLAB to achieve a typical non-periodic signal frequency domain analysis 2, using MATLAB to achieve signal amplitude modulation 3, using MATLAB for signal Fourier transform nature of the simulation waveform )
