《模式识别与智能计算》部分函数的源程序 第四章(Part of the function of the source of Pattern Recognition and Intelligent Computing)

说明：  产生一个chirp信号，给出时域及频域特性。利用匹配滤波器进行滤波。如果有延时也能正确滤波。(Generate a chirp signal, given the time domain and frequency domain characteristics. Filtering using matched filter. If there is delay filter can correct.)

说明：  遗传算法，MATLAB编的程序，希望对大家有用，所以传上来大家共享(Genetic algorithm, MATLAB allocation procedure, in the hope that useful, so Chuan-up share)
