completeDFT: Complete DFT

Description

Function to calculate the complete DFT.

Usage

completeDFT(x, freq = 2 * pi * (1:length(x))/length(x), ...)

Arguments

x

time series vector.

freq

frequency vector.

Arguments used in the predictiveDFT function.

Value

Complex valued complete DFT vector.

Details

The default frequencies are 2*pi*(1:n)/n, where n is a length of a time series.
