说明：  EMD的子程序，刚刚忘记了不好意思，真的不是为了刷程序数量(EMD of the subroutine, just forget I am sorry, do not amount to brush program)

指纹识别的matlab程序，里面包括了一些指纹图片，利用gabor小波进行识别(Fingerprint recognition matlab program, which includes a number of fingerprint images using gabor wavelets to identify)

鲁棒性好，性能优越，PLS部分最小二乘工具箱,算法优化非常好，几乎没有循环。( Robustness, superior performance, PLS PLS toolbox, Algorithm optimization is very good, almost no circulation.)

单一频率的正弦相关法动态测试系统的测试方法简单，不需要对系统进行辨识。只需要观察被测系统输出信号的相差和幅值变化。通过扫频的方法测量在不同的频率点下的幅值和相位变化。在工程应用中，只需要知道被测系统的相位变化在正常的范围内就可以视系统的动态性能正常。该仿真算法只是建立了一个模型。在实际运用时还需要变换测试信号的频率和周期。(A single frequency sinusoidal correlation method of testing dynamic testing system is simple, does not require system identification. Only need to observe the difference between the measured system output signal and amplitude change. Swept through the method of measurement points at different frequencies under the amplitude and phase changes. In engineering applications, only need to know the system under test changes in the normal phase it may be possible within the framework of the dynamic performance of the system to normal. The simulation algorithm is the establishment of a model. In the practical application of test signals also needed to change the frequency and periodicity.)

计算信号里的信噪比的程序，用在数字信号分析中和振动信号处理等方面(The function SNR get the signal to noise (SNR) ratio)

说明：  本程序用于实现求解并绘制正弦信号功率谱密度的功能(procedures used to achieve the solution and the mapping of sinusoidal signal power spectral density function)
