%description
Functions that allow you to generate and compare power spectral density
(PSD) plots given time series data. Fast Fourier Transform (FFT) is used
to take a time series data, analyze the oscillations, and then output the
frequencies of these oscillations in the time series in the form of a PSD
plot.Thus given a time series, the dominant frequencies in the time series
can be identified. Additional functions in this package allow the dominant
frequencies of multiple groups of time series to be compared with each
other. To see example usage with the main functions of this package,
please visit this site:
<https://yhhc2.github.io/psdr/articles/Introduction.html>. The
mathematical operations used to generate the PSDs are described in these
sites: <https://www.mathworks.com/help/matlab/ref/fft.html>.
