说明：  Matlab教程，包括Matlab符号与数值运算、Matlab绘图、Matlab程序设计及其工程运用等内容(Matlab tutorials, including Matlab symbolic and numerical computation, Matlab graphics, Matlab programming and engineering application, etc.)

This document is useful for hearing sound classification

双站SAR成像的例子，里面解决了非线性问题(an example of bisar,in order to deal with the nonlinear problem)

考虑不同频率复用因子的情况下用户的容量和SINR值变化情况，得出在FRF为3的情况下达到最大的值(calculate the edge user under different frequence reuse factor the performance of capacity and SINR. The result is that when FRF equals to 3 achieve the maximum value.)

说明：  基于能量检测和周期循环检测的认知无线电频谱检测matlab代码 用周期循环检测算法检测： 首先运行a.m程序，通过此程序运算得出循环频率a值； 再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； 用能量检测算法检测： 运行nengliang.m检测程序，使用能量检测对信号进行检测。 检测完毕，对检测性能进行分析。 (Cognitive radio based on energy detection spectrum detection matlab code)

说明：  1到40的无重复随机抽样的程序，其中抽取数目为参数，可调节(1 to 40 repeated random sampling procedure, which extract the number of parameters can be adjusted)

scilab,开源数值计算方针软件。实现不同信噪比条件下的频域变换仿真程序，可完美兼容matlab。(Scilab, open source software for numerical calculation principle. Than the frequency domain transform simulation program under different signal-to-noise to achieve, can be perfectly compatible with matlab.)

matlab的例程cfdlms，请大家多多指教(matlab routine cfdlms, please everyone exhibitions)

用matlab实现飞机的模拟飞行并有简单的控制操作(Matlab simulation with the flight of aircraft)

说明：  这是一个伽玛图像校正程序，首先读入原始图像，然后利用事先在matlab中计算得到的对每个灰度值校正后的数值替代原灰度值即可。(this is a gama image revising program. it uses revised grey level obtained from matlab to substitute original image data to fulfill this task.)
