本程序能够计算两个信号的频域相干函数和两个信号的互功率谱。(This procedure is able to calculate the two signals in the frequency domain coherence function and the two signals cross-power spectrum.)

采用c++调用matlab写的一个sift算法，其中调用matlab只是使用其中几个函数。可以很准确的检测出sift特征点。(Using c++ to call a matlab write sift algorithm, which used to call only a few matlab function. Can accurately detect the feature points sift.)

非线形混沌系统的庞加莱图的画法的代码以及其MATLAB m文件代码(Non-linear chaotic system Poincare map of the painting of the code and its MATLAB m-file code)

this source code is very well

用小波去噪，不同尺度下的阀值去噪，去噪效果的对比很不错(Using wavelet denoising, different scales of threshold denoising, contrast denoising effect is very good)
