This package implements fast compressed sensing using structurally random matrices (SRM) described in [1] and [2]. As the package is still under development any comments or bug reports are highly welcome.

关于matlab中的众多函数，及相对应的作用介绍，便于查找和记忆(With regard to the many functions in matlab, and the corresponding role of the introduction, easy to find and remember)

matlab的经典书籍,这是一本很好的书。将会很好的帮助你学习matlab 语言。(matlab s classic Book,please come on ,this is best,the book is really very good,if you download it,then it will help you!)

截取一段音频信号作为输入信号，分别通过低通，高通和带通滤波器，比较滤波效果。(Interception of an audio signal as an input signal, respectively, through a low pass, high pass and band-pass filter, compare filtering effect.)

This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

介绍了各种小波函数，包括提取一维小波变换低频系数，计算完整最佳小波包树，求小波中心频率等函数的函数名(Describes the various wavelet functions, including a one-dimensional wavelet transform to extract the low-frequency coefficients to calculate the optimal wavelet packet complete tree, seeking the center frequency of the wavelet function names)

说明：  x=2*sin(4*pi*t)+5*cos(8*pi*t) 对其进行快速傅立叶变换 加入高斯噪声 再进行频谱分析(x = 2* sin (4* pi* t) 5* cos (8* pi* t) makes its rapid Fourier transform to re-Gaussian noise spectral analysis)

It s about smart antenna. It can help you whatever it is.
