Macro arr_rs::array_eye

macro_rules! array_eye {
    ($n:expr) => { ... };

Create new 2d array with ones on the diagonal and zeros elsewhere

Examples

use arr_rs::prelude::*;

let arr: Result<Array<i32>, ArrayError> = array_eye!(2, 3, 3);
assert_eq!(vec![2, 3], arr.get_shape().unwrap());
let arr: Result<Array<i32>, ArrayError> = array_eye!(4, 5, 3);
assert_eq!(vec![4, 5], arr.get_shape().unwrap());
