将格式为rgb的数字图像转换成格式为hsi的数字图像，方便简单，操作容易(change rgb image into hsi image)

不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)

说明：  BA无标度网络的算法，主要是演示无标度网络是怎么样生成新节点的(BA scale-free network algorithm, the main is to demonstrate how the scale-free network to generate a new kind of node)

二维FDTD仿真高斯脉冲在平面内的传播，并且设定了PML边界条件，可以自动生成关于Ez，Hx和Hy的.avi文件，播放脉冲动态传输。(Dimensional FDTD simulation Gaussian pulse propagation in a plane, and set the PML boundary conditions, can automatically generate .avi files on Ez, Hx and Hy, and play dynamic pulse transmission.)

基于Xilinx System Generator的Simulink仿真代码(Based on the Xilinx System Generator Simulink simulation code)

对802.11a物理层进行了仿真，我还没有仔细看，压缩包中有两个文件夹，一个是R13，另一个是R13SP1，好像是用simulink仿真出来的(802.11a physical layer of the simulation, I have not carefully watch, compressed package has two folders, one is R13, the other is R13SP1, seems to be out of use simulink simulation)

arma模型的matlab实现，word格式(arma model matlab implementation)

图像处理中，HOUGH变换的实验程序，用MATLAB编写，配有可是图片(image processing, HOUGH transform the experimental procedure, using MATLAB, but equipped with photo)

数学建模公交线路问题 该程序利用迪杰斯特拉算法经行求解，使用该代码前最好先阅读Readme.doc(Bus lines mathematical modeling problem using Dijkstra algorithm for the program through the line solution, a good idea to use the code to read Readme.doc)

This tests the new String object method: concat.
