filterdesign

这是一个计算复杂网络参数closeness centrality 的程序，已调试(this program is used to caltulate closeness centrality)

设计巴特沃斯和切比雪夫滤波器，实现低通滤波，并计算滤波系数，给出效果图(Design a 20-order Butterworth filter, low-pass filter, and the filter coefficient calculation gives renderings)

Matlab图形图像处理函数命令Graphics and Image Processing Matlab function commands(Graphics and Image Processing Matlab function commands Graphics and Image Processing Matlab function commands)

测试文本，选用著名的gettysburg这篇英文文本做为测试文本(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)
