Function fft

src/signal/mod.rs:504–515

Fast fourier transform for 1d signals # Parameters - `input` is the input Array - `norm_factor` is the normalization factor with which the input is scaled before the transformation is applied - `odim0` is the length of output signals - used for either truncating or padding the input signals # Return Values Transformed Array

(input: &Array<T>, norm_factor: f64, odim0: i64)
