.fft {fftab} | R Documentation |
Compute the Fast Fourier Transform (FFT) of a Vector
Description
Computes the Fast Fourier Transform (FFT) of a numeric vector. Optionally, normalizes the result by dividing it by the length of the input vector.
Usage
.fft(x, norm = FALSE)
Arguments
x |
A numeric vector representing the input signal to transform. |
norm |
A logical value indicating whether to normalize the FFT output
by dividing it by the length of the input vector. Default is |
Details
This function wraps around the base R stats::fft
function and provides an
option for normalization.
Value
A complex vector representing the FFT of the input signal.
