描述光在非线性介质中的传输，用的方法为分布付里叶方法。(Described in the non-linear optical transmission medium, the methodology used for the distribution of Fourier methods.)

Echelon factorization A = c a b.

说明：  Time Frequency Toolbox matlab时频分析工具箱,里面有各种时频分析函数，用matlab实现的，小波变换，Gabor变化，短时傅里叶变换等等(AF Ambiguity function AR Auto-regressive (filter or model) ASK Amplitude shift keyed signal BJD Born-Jordan distribution BPSK Binary phase shift keyed signal BUD Butterworth distribution CWD Choi-Williams distribution FM Frequency modulation FSK Frequency shift keyed signal GRD Generalized rectangular distribution HT Hough transform MHD Margenau-Hill distribution MHSD Margenau-Hill-Spectrogram distribution MMCE Minimum mean cross-entropy NAF Narrow-band ambiguity function PMHD Pseudo Margenau-Hill distribution PWVD Pseudo Wigner-Ville distribution QPSK Quaternary phase shift keyed signal RID Reduced interference distribution STFT Short-time Fourier transform TFR Time-frequency representation WAF Wide-band ambiguity function WVD Wigner-Ville distribution ZAM Zhao-Atlas-Marks distribution)

说明：  这是一个小巧的指针类.在这里提供了两个主类CountedPtr和BackPtr,可以使用在任何环境中(This is a small target category. Here the two main categories CountedPtr BackPtr and can be used in any environment)

cwpinpu.m为连续波频谱 lfmpinpu.m为线性调频频谱 nlfmpinpu.m为非线性调频频谱 对研究信号频谱分析很有帮助(cwpinpu.m for continuous wave spectrum lfmpinpu.m of chirp spectrum nlfmpinpu.m for nonlinear FM spectrum of research signal spectrum analysis helpful)

Matlab basics are explained to brief the concepts in details

说明：  WPAN国际标准IEEE802.15发布的信道模型的MATLAB源码。包括几种室内和室外模型。都是基于改进的SV模型。应用在短距离超宽带UWB无线通信中。 (WPAN IEEE802.15 international standards issued by the channel model of MATLAB source. Several, including indoor and outdoor models. Improvements are based on the SV models. Application short distance UWB UWB wireless communications.)

说明：  基于matlab的子程序，可以进行任意通信信号的升余弦滤波(Subroutine based on matlab, any communication signals can be raised cosine filter)

Mixture of Gaussian is an example of matlab code that plot miture of more than one gaussian.
