ROUGH-SET

to help in computer vision ,pattern recognition and machine learning research for grad students in image analysis and computer science works of masters and doctorate

主要介绍了MATLAB命令，并对其进行了一定总结。对掌握相应的函数有所帮助。(Mainly introduces the MATLAB command, and gain a certain sum. Corresponding function of the master help.)

some source code on nichols and bode using matlab

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

This simulation file is in matlab software and is about the pwm closed loop chopper.

一个实现对直升机进行飞行控制的程序，包括俯仰控制、滚转控制等。(A realization on the helicopter flight control procedures, including pitch control, roll control.)

以短时傅里叶变换为基础，进行信号的时频分析，可以在做出三维瀑布图。(In short time Fourier transform as the foundation, carries on the signal of time-frequency analysis, we can make 3 d waterfall diagram )

大地电磁二维正演程序是电磁法的基础编程，首先设置地电断面然后通过正演模拟电磁场在大地中的传播形式来得到地下地质体的电阻率情况，从而得到地下地质体情况(Two-dimensional magnetotelluric forward modeling procedure is based programming electromagnetic method, first set the geoelectric section and then through the forward modeling electromagnetic propagation in the earth in the form to get the subsurface resistivity body condition, resulting in underground geological conditions)

基于xilinx的cfr3.0核的仿真模型文件，对研究cfr对各种制式的信号的肖峰有不错的参考价值(The simulation model based on xilinx cfr3.0 nuclear file, studying the signal of the CFR of various formats XiaoFeng has good reference value)
