 Fourier amplitude spectrum

 [F,U] = FASP(DT,XGTT)

 Description
     Fourier amplitude spectrum of an acceleration time history.

 Input parameters
     DT [double(1 x 1)] is the time step of the input acceleration time
         history XGTT.
     XGTT [double(1:numsteps x 1)] is the input acceleration time history.
         numsteps is the length of the input acceleration time history.

 Output parameters
     F [double(1:2^(nextpow2(length(XGTT))-1) x 1)] is the frequency range
         in which the Fourier amplitudes are calculated.
     U [double(1:2^(nextpow2(length(XGTT))-1) x 1)] contains the Fourier
         amplitudes
