本代码设计的切比雪夫1型滤波器，与MATLAB中的切比雪夫滤波器不同的是输出为未归一化的零极点，输入只要是通带频率，通带波动，截止频率，阻带衰减即可，更便于抄做(The code design of Chebyshev Type 1 filter, and MATLAB in the Chebyshev filter output is not different is that the poles and zeros of the normalized input as long as the pass-band frequency, pass-band fluctuations, cutoff frequency, stopband attenuation can be more easily copied to do)

上硕士时用过的信号处理的Matlab代码，主要包括DFT、FFT变换滤波器设计、Matlab下的数字信号处理示例等内容，比较适合余初学者，谢谢。(When used on the master signal processing Matlab code, including DFT, FFT transform filter design, Matlab example under the digital signal processing, etc., more than suitable for beginners, thank you.)

复杂网络拓扑生存算法，对可能出现的拓扑不连通的状况进行了考虑，并支持网络拓扑的动态变化(Survival of a complex network topology algorithm, consider the situation that may appear disconnected topology and supports dynamic changes in the network topology)

这是居于matlab下，7.4用汉明窗、布莱克曼窗设计滤波器，7.5是用Kaiser窗设计滤波器(The example 7.4 is use Hamming hamning blackman design of the lower filter,and the 7.5 is use Kaiser)
