Performs fast fourier transform on wave elevation time-series and outputs dominant frequencies & corrosponding power spectrum values.
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:
- eta – wave elevation time series
- Fs – sampling frequency
- Units – toggle (1: Hz | 2: rads/s)
- Peaks – number of peaks of interest from transform
Outputs:
- Ap – amplitude of peaks
- fp – frequency value of transform peaks, in units specified by input 3.
