合成孔径雷达SAR成像很全面的matlab程序，非常不错(SAR synthetic aperture radar imaging very comprehensive matlab program, very good)

Matlab code to detect tumour in brain scan

三种基本协作方式仿真，协作频谱感知。很适用，希望大家下载。(Are three basic ways to collaborate simulation, cooperative spectrum sensing. Very applicable, I hope you download.)

说明：  对数据进行因子分析，得到的是降维的结果。可用来做基本的降维，故障诊断，图像分解(Through factor analysis of the data, we get the result of dimension reduction)

屏幕上不停地出现随机（随机颜色，随机边长，随机线宽）的三角形(Constantly appear on the screen randomly (random color, random side, random width) of the triangle)

采用matlab编写的steffensen迭代法(Steffensen prepared by iteration matlab)

说明：  给定入射信号角度分别为 -22度 ，6度，18度时，不同信噪比情况下各种空间谱估计算法得到的曲线图(given incident signals point to-22 degrees, 6 degrees, 18 degrees, the signal to noise ratio under different space spectral estimation algorithm of the curve)

多网格求解泊松方程，给出并解释了一个如何使用多网格求解的过程(I give a short explanation of how to use multigrid to solve the Poisson equation in cylindrical coordinates for a solid conducting pipe. I also explain how to use a non-uniform grid to optimize the problem. )

这个是基于matlab制作的KNN 识别器的写法(This is K-Nearest Neighbour classifier used in pattern recognition.)

SUBROUTINE Gauss 高斯消去法的子程序 分享给大家(SUBROUTINE Gauss_Expunction a methed to solve matrix )
