用matlab实现二相编码信号与线性调频信号相结合的信号的画法，以及模糊函数，频谱的画法(Matlab code used to achieve two-phase signal and the combination of LFM signal of painting, and the fuzzy function, the spectrum of the painting)

说明：  某班准备从5名游泳队员中选择4人组成接力队，参加学校的4×100m混合游泳接力比赛。 5名队员4种泳姿的百米平均成绩如下表，问应如何选拔队员组成接力队？(Classes to prepare a swim team from the five-member Select 4 relay team, participated in the School of the 4 × 100m relay swimming race mixing. Five members of the four kinds of strokes average 100 meters in the following table and asked how the composition of the selection of relay team members?)

基于凸优化算法，频率分集阵列天线在全时空域内可控点聚焦，实现对动目标追踪、多目标聚焦，可用于实现点对点秘密通信(Based on convex optimization algorithm, the frequency diversity array antenna can focus on controllable points in the whole time and space domain, and can be used to realize point to point secret communication.)

说明：  这是有关信道编码的matlab仿真程序，里面有很多子程序，很好用！(This is the channel coding of Matlab simulation program, there are many subroutine good use!)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

视频格式转换，包括mpeg转为yuv和yuv格式的352*288插值为704*576.其中mpeg转为yuv需要调用文件夹中的两个dll(此为matlab工具箱提供)(Video format conversion, including mpeg to yuv and yuv format 352* 704* 288 interpolated to 576. Yuv to mpeg which folder you want to call the two dll (This is provided matlab toolbox))

This matlab code calculates the channel capacity over AWGN channel and the ergodic channel capacity over Rayleigh fading channel.

matlab的拟合插值经典算法，可用于数学建模(matlab development of classical planning algorithms can be used for mathematical modeling)

Z bus building algorithm

This program basically count every character that is in a text. The program opens de text an reads it, stores data in a matrix and count characters that are in Ascii code and writes the results in a new text file
