Examples

use crate::ndarray::array;
use scirs2_core::ndarray_ext::mask_select;

let a = array![[1, 2, 3], [4, 5, 6]];
let mask = array![[true, false, true], [false, true, false]];
let result = mask_select(a.view(), mask.view()).expect("Operation failed");
assert_eq!(result.shape(), &[3]);
assert_eq!(result[0], 1);
assert_eq!(result[1], 3);
assert_eq!(result[2], 5);
