Note: Description accessible with Matlab's built-in "help" function.
The function solveWaveFFT(eta,Fs,units,peaks) computes and plots the 1-sided spectrum from the fast fourier transform of a given time series signal (eta). This function utilizes Matlab's built-in fft function.
Inputs:
  1. eta – wave elevation time series
  2. Fs – sampling frequency
  3. Units – toggle (1: Hz | 2: rads/s)
  4. Peaks – number of peaks of interest from transform
Outputs:
  1. Ap – amplitude of peaks
  2. fp – frequency value of transform peaks, in units specified by input 3.
