Function digitize 

pub fn digitize<T>(
    array: &Array<T>,
    bins: &Array<T>,
    right: bool,
) -> Result<Array<usize>>
where
    T: Float + Clone + PartialOrd,

Return indices of bins to which each value belongs

Parameters

• array - Input array
• bins - Array of bin edges (must be monotonically increasing)
• right - If true, intervals include right edge; otherwise left edge

Returns

Array of indices indicating which bin each value belongs to

Examples

use numrs2::prelude::*;

let x = Array::from_vec(vec![0.2, 6.4, 3.0, 1.6]);
let bins = Array::from_vec(vec![0.0, 1.0, 2.5, 4.0, 10.0]);
let indices = digitize(&x, &bins, true).expect("digitize should succeed");
assert_eq!(indices.to_vec(), vec![1, 4, 3, 2]);
