beam

This file can be used in matlab to implement easy fft. it is very effective and good method to implement easy fft.

将输入的灰度图像转化为RGB伪彩色图像进行输出。在Matlab中编程实现！(importation of gray RGB images into pseudo-color image output. In Matlab programming!)

说明：  little matlab script but still no error

压缩感知的仿真算法，使用的是SOMP恢复算法。(Compressed sensing simulation algorithm, using SOMP recovery algorithm.)

Specify the condition to stop the decoding iterations as one of Maximum iteration count | Parity check satisfied . The default is Maximum iteration count . When you set this property to Maximum iteration count , the object will iterate for the number of iterations you specify in the Maximum Iteration Count property. When you set this property to Parity check satisfied , the object will determine if the parity checks are satisfied after each iteration and stops if all parity checks are satisfied.

此程序为基于时域有限差分法的matlab程序，主要是计算二维MUR吸收方柱散射(This procedure is based on finite difference time domain method matlab program, mainly of two-dimensional scattering MUR absorbing square columns)

simple lattice Boltzmann code in matlab

用matlab生成正态随机数,用于数理统计及概率中(to produce the random matrix with matlab)

产生多径衰落信道，有6个可分辨径，每径中有25个径形成瑞利信道。(Generate multi-path fading channel, there are six tracks can be distinguished, each track has 25 tracks form a Rayleigh channel.)

模式分类中的特征选择,希望大家可以参考一下.(Pattern Classification in feature selection, hope that we can reference.)
