该段代码可用于加速度信号的积分求得位移。使用的是频域积分方法，设置合适的上下限截止频率可较好的复现实际路面的位移高程。-This code can be used for integration of the acceleration signal obtained displacement. Using a frequency-domain integral method, set the appropriate upper and lower cutoff frequency displac

matlab下，通过频域积分将加速度积分至速度后，再次积分至位移。(Integration from acceleration to displacement.)

matlab对信号的处理，主要是针对振动信号的处理，包括加速度积分到位移，时域经快速傅里叶变换到频域(The signal processing of MATLAB is mainly aimed at the processing of vibration signal, including acceleration integral to displacement, time domain and FFT to frequency domain)

利用labview实现加速度信号的频域积分(Acceleration signal realization in frequency domain integration)
