给出了三个m文件，分别适用于不同的Shortestpath问题，本程序是工程CT的一部分，属于正演算法，可获得射线路径。每一条均有注释，适合初学者。完美运行。(For the Shortpath, given 3 m files. They are the part of CT for induction. Fit for green hands.)

自己编写的MATLAB系统里没有的拉格朗日插值的源函数程序(Write your own MATLAB system the source of the Lagrange interpolation function program)

说明：  合成孔径雷达的距离多普勒成像算法的源代码，简单易懂，适合新手与初学者。(Distance synthetic aperture radar Doppler imaging algorithm source code, easy to understand for novice and beginners.)

D-S证据理论数据融合，对球谐函数图形进行仿真,数学方法是部分子空间法。( D-S evidence theory data fusion, Of spherical harmonics graphic simulation, Mathematics is part of the subspace.)

routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use: >> n = 100 number of data points >> dt = 0.01 spacing between samples >> t = 0:dt:(n-1)*dt time vector >> y = sin(2*pi*10*t) 10 Hz sin wave >> fft_plot(y,dt) plot of signal in time and frequency domain
