FuctionKey
说明：一个matlab mex 文件，可以用来在matlab程序中捕捉用户按下的特殊功能健：F1, ..., F12. 使用时，在你的应用程序的 KeyPressFcn的函数体里，是用wgfcnkey，根据其返回值，判断是否有功能健被按下。(a Matlab mex documents, in Matlab can be used to capture user proceedings of the special features? Kin : F1, ..., F12. When used in your application's function KeyPressFcn the body, is wgfcnkey, return value, determine whether there is any function Kin is pressed.)

用FFT计算信号的功率谱密度时，需要先计算FFT，再计算双边谱密度，然后计算单边谱密度。在matlab里注意FFt要除以采样点数，计算双边谱时要注意除以频率分辨率。 ( When calculated using the FFT power spectrum density signal, you need to calculate the FFT, and then calculate the bilateral spectral density, and then calculate the unilateral spectral density. In matlab in Note FFt divided by sampling points should be noted when calculating the bilateral spectrum divided by the frequency resolution.)
