Trait basic_dsp_vector::FrequencyDomainOperations[−][src]

pub trait FrequencyDomainOperations<S, T> where
    S: ToSliceMut<T>,
    T: RealNumber, {
    fn mirror<B>(&mut self, buffer: &mut B)
    where
        B: for<'a> Buffer<'a, S, T>;
    fn fft_shift(&mut self);
    fn ifft_shift(&mut self);
}

Defines all operations which are valid on DataVecs containing frequency domain data.

Failures

All operations in this trait set self.len() to 0 if the vector isn't in frequency domain and complex number space.

Required Methods

`fn mirror<B>(&mut self, buffer: &mut B) where B: for<'a> Buffer<'a, S, T>,`

This function mirrors the spectrum vector to transform a symmetric spectrum into a full spectrum with the DC element at index 0 (no FFT shift/swap halves).

The argument indicates whether the resulting real vector should have 2*N or 2*N-1 points.

Example

use basic_dsp_vector::*;
let mut vector = vec!(1.0, 2.0, 3.0, 4.0, 5.0, 6.0).to_complex_freq_vec();
let mut buffer = SingleBuffer::new();
vector.mirror(&mut buffer);
assert_eq!([1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 5.0, -6.0, 3.0, -4.0], &vector[..]);

`fn fft_shift(&mut self)`

Swaps vector halves after a Fourier Transformation.

`fn ifft_shift(&mut self)`

Swaps vector halves before an Inverse Fourier Transformation.

Implementors
