产生随机导频信号的程序 能利用此基本的来帮助进行复杂的编程(Generate random pilot signal)

参考国外网站资料，自己实现的海宁窗滤波函数。滤波测试图像为matlab自带的cameraman.tif图片。(Hanning filter program in Matlab)

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )

说明：  用matlab编写的快速纽曼算法，用于社团检测，对于不太复杂的网络分类效果很好(Prepared using matlab Newman fast algorithm for detecting community, for less complex network classification works well)

将弹性波模拟得到的grd格式的数据读取到matlab中，可以读取二进制格式和ASCII格式的数据。(read*.grd files into matlab)

说明：  此為用來計算特徵向量值以及特徵向量的程式(Eigenvalue and eigenvector calculate)

Designs an FIR filter given a desired frequency response H_des(w). The design is judged by the maximum absolute error (Chebychev norm). This is a convex problem (after sampling it can be formulated as an SOCP). minimize max |H(w) - H_des(w)| for w in [0,pi] ( where H is the frequency response function and variable is h (the filter impulse response). )

可行方向法，用于无约束优化的作业所制作，请大家指教(Possible direction method, used for unconstrained optimization of assignments)
