Function information::hist::hist2d

pub fn hist2d(
    arr_a: &Array1<usize>,
    arr_b: &Array1<usize>,
    nbins_a: usize,
    nbins_b: usize
) -> Result<Array2<usize>>

Calculates the event intersection between two integer arrays of equal size

Usage

use ndarray::array;
use information::hist2d;

let arr_a = array![0, 1, 1, 1, 2, 2];
let arr_b = array![1, 0, 0, 1, 2, 3];
let expected = array![
    [0, 1, 0, 0],
    [2, 1, 0, 0],
    [0, 0, 1, 1]
];
let hist = hist2d(&arr_a, &arr_b, 3, 4).unwrap();
assert_eq!(hist.shape(), &[3, 4]);
assert_eq!(hist, expected);
