Trait basic_dsp_vector::ReorganizeDataOps [−] [src]

pub trait ReorganizeDataOps<T> where
    T: RealNumber, {
    fn reverse(&mut self);

    fn swap_halves(&mut self);
}

This trait allows to reorganize the data by changing positions of the individual elements.

Required Methods

Reverses the data inside the vector.

Example

use basic_dsp_vector::*;
let mut vector = vec!(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0).to_real_time_vec();
vector.reverse();
assert_eq!([8.0, 7.0, 6.0, 5.0, 4.0, 3.0, 2.0, 1.0], vector[..]);

This function swaps both halves of the vector. This operation is also called FFT shift Use it after a plain_fft to get a spectrum which is centered at 0 Hz.

swap_halvesb requires a buffer but performs faster.

Example

use basic_dsp_vector::*;
let mut vector = vec!(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0).to_real_time_vec();
vector.swap_halves();
assert_eq!([5.0, 6.0, 7.0, 8.0, 1.0, 2.0, 3.0, 4.0], vector[..]);
