Trait FrequencyDomainOperations

pub trait FrequencyDomainOperations<S, T>
where
    S: ToSliceMut<T>,
    T: RealNumber,
{
    // Required methods
    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!(Complex::new(1.0, 2.0), Complex::new(3.0, 4.0), Complex::new(5.0, 6.0)).to_complex_freq_vec();
let mut buffer = SingleBuffer::new();
vector.mirror(&mut buffer);
assert_eq!([Complex::new(1.0, 2.0), Complex::new(3.0, 4.0), Complex::new(5.0, 6.0), Complex::new(5.0, -6.0), Complex::new(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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
