chirp信号产生比较 If you are aware of this and would still like to have a pseudo-chirp then you can take a look at the example below. I show the difference between trying to generate the type of chirp you are after and a real chirp signal. I also plot the derivative of the resulting signals, so I can highlight that between half cycles you will have a sometimes subtle (sometimes not so subtle) jump in gradient.

利用matlab 做拟合的图表 两个序列进行拟合 并画出拟合后的图和残差 另外作图的过程是每次都取相同的一段数据 且起始点不断往后推(Using matlab to do a chart to fit the proposed merger of two sequences and residual process diagram plotting another draw after fitting is always take the same piece of data and constantly pushed back the starting point)
