水平集做图像分割的一个源程序，大家可以参考(levelset method)

详细的介绍了FDTD进行数学建模分析的相关数学理论知识。(A detailed description of the FDTD related mathematical theory knowledge of mathematical modeling analysis.)

计算圆阵方向图，可任意设置阵元个数和信号频率；并汇出三维图、二维方向图以及等高线图(Calculating circular array pattern can be arbitrarily set the number of array elements and signal frequency and export three-dimensional map, two-dimensional pattern and contour plots)

The two dimensional LMS program is used to enhanced image contrast by adaptive filtering process, it operates on every fixel through each row and column

这是初学真学习SINS的好程序，里面有较详细的注释，方便读懂程序。(This is a good beginner really learn SINS program, which has more detailed notes, easy to read program.)

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)

离散傅里叶变换的子程序，matlab的built in函数的一部分程序(Discrete Fourier Transform subroutine built in matlab function part of the program)

mbd project control systems, hope this helps people
