Maple11 官方使用手册 详细讲解maple11(Maple 11 user Manual)

说明：  OFDM源代码，基于MATLAB系统仿真(OFDM simulation source code)

音频信号采集 根据二进制编码原则，实现音频信号的信息采集(AUODIO CATCH)

This it the code to describe rayleigh distribution

产生16路信号，画出16路原始信号的频谱叠加图以及滤波器响应，并画出结果信号的时域和频域波形(Generate 16-channel signal, draw 16 original signal spectrum overlay and a filter response, and draw result signals in time domain and frequency domain waveforms)

说明：  这是一个matlab科学计算的初步实验。对初学matlab的人有一定的帮助(This is a preliminary experiment matlab scientific computing. Matlab for beginners who have some help)

一种常用的关于信号稀疏度测试的指标，值得拥有。(A commonly used test for signal sparsity indicators, worth having.)

实现图像rgb空间和hsi空间的相互转化，matlab不带这两个函数(rgb to hsi space program and hsi to rgb space program)

说明：  蚁群算法混合粒子群算法的matlab程序(Matlab Program of Ant Colony Algorithm Mixed Particle Colony Algorithm)

实现arnold置乱，其中利用到置乱周期，是图像置乱的不错程序。(Achieve arnold scrambling, which take advantage of scrambling cycle, the image scrambling for a good program.)
