球函数可视化， 在MATLAB环境下实现求函数的可视化，分实部和虚部作图-Global visual function in the MATLAB environment to achieve the visual demand function, the real and imaginary parts of sub-plot

This function alculates Fourier Amplitude spectra of the time series of uncorrected acceleration and velocity depending on the FFTformat argument and produce a plot.Visual inspection of the fas is helpful for setting a low cut frequency in filter des
