TWO-STAGE-DEA

It is very imoprtant I hope it could help you

这是一章山西大学物理系开的matlab课程的课件(This is a Department of Physics, Shanxi University chapter of matlab programs open courseware)

雷达仿真的源程序，功能齐全，添加了界面，易于使用。(Radar Simulation of the source, fully functional, add the interface easy to use.)

数字信号处理中自适应滤波的实现，简单实用(Digital signal processing in the realization of adaptive filtering, simple and practical)

说明：  matlab中微分方程的解法，及其应该注意的问题(matlab in the solution of differential equations, and should pay attention to the issue of)

信道编码的相关源码,包括检错码,线性分组码,卷积码,Turbo码和低密度校验码(LDPC).(Source, channel coding error detection code, linear block codes, convolutional codes, Turbo codes and low density parity check code (LDPC).)

是一个基于遗传算法改进的模糊C均值算法，很不错的代码。(It is a improved fuzzy C-means algorithm based on genetic algorithm , a very good code. )

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)

TOOLBOX_calib找来的matlab工具包，图像标定等(TOOLBOX_calib found the matlab toolkit, image calibration, etc.)
