用matlaB实现混响，其中有单回声，多重回声，无穷回声及全通混响的程序代码(reverberation by matlab)

说明：  根据滚降系数画出滚降系统频谱，并画出相应的时域波形(According to the roll-off factor to draw the spectral roll-off and draw the corresponding time-domain waveform)

在matlab中直接调用的doolittle分解、改善的平方根法分解、追赶法分解小程序(Small program can be called directly in matlab，including doolittle decomposition method，improved square root of decomposition and catching decomposition method using in triangular matrix decomposition)

基于hough变换，圆心检测，可达亚像素级别，简单易用，可显示圆心坐标和图像圆心所在位置。解压即可用。main为主程序(Hough transform center detection, with sub-pixel level, easy to use, can display the location of the center coordinates and image the center. Decompression can be used. main main program)

此程序段能完整画出所要图形曲线的蛛网图，其它网站上基本没有提供，对学习经济控制问题是个很有帮助的的功能程序。(This program segment to be able to draw a complete graph of the cobweb diagram, other sites basically did not provide for the study of economic control issue is a useful feature programs.)

用Arnold方法对图像进行置乱，目的使图像随机分布均匀(Arnold method using the image scrambling, the purpose of uniform random distribution of the image)
