模拟产生（7，4）汉明码及其监督矩阵，并用产生的监督矩阵判断传输的码字是否有错，如果有错，指示出其出面错误的位置 (Simulated (7,4) Hamming code and its monitoring matrix, and supervision of the resulting matrix to judge transmission codeword is wrong, if wrong, indicating that it came forward to the wrong location)

non linear B spline curve fitting

本程序可以实现具有较好相关性的ZC序列，其时频两域相关性很强(The program can achieve better correlation with the ZC sequence, time and frequency domain strong correlation)

说明：  本程序运行需一个小时左右。优化准则是旁瓣电平最小。取栅格间距为lemda/2,阵元间距为栅格间距的整数倍。放阵元的位置放1，否则放0(This program should be running an hour or so. Rule of optimization is side-lobe level minimum. Take grid spacing for lemda/2, spacing for grid spacing array (integer times. Put the position of the array (put 1, otherwise put 0 )

交流得到的matlab图像去模糊的一个验证程序，还算是比较详细。(A verification process exchanges get matlab image deblurring, still is relatively detailed.)

基本原理就是首先求解出连续系统微分方程的近似解，然后对系统的Jacobian矩阵进行QR分解，计算Jacobian矩阵特征值的乘积，最后计算出LE和分数维(The basic principle is to first find the approximate solution of differential equations continuous system, then the system will be on the Jacobian matrix QR decomposition product Jacobian matrix computing eigenvalues, and finally calculate the fractal dimension LE)

MUSIC算法。可进行波达方向估计（DOA），并进行高分辨率现代谱估计。(MUSIC algorithm. DOA can be estimated (DOA), and modern high-resolution spectral estimation.)

matlab 读取grib格式数据程序，read_grib1.4.0(read grib1 by matlab )

完整版的频谱检测算法的MATLAB实现，有原理，有程序，有结果。(Full version of the spectrum to achieve detection algorithm of MATLAB, there are principles, procedures and results.)
