arrayfire::max_ragged - Rust

pub fn max_ragged<T>(
    input: &Array<T>, 
    ragged_len: &Array<u32>, 
    dim: i32
) -> (Array<T::InType>, Array<u32>) where
    T: HasAfEnum,
    T::InType: HasAfEnum, 

Max reduction along given axis as per ragged lengths provided

• input contains the input values to be reduced
• ragged_len array containing number of elements to use when reducing along dim
• dim is the dimension along which the max operation occurs

Tuple of Arrays:

• First element: An Array containing the maximum ragged values in input along dim according to ragged_len
• Second Element: An Array containing the locations of the maximum ragged values in input along dim according to ragged_len

use arrayfire::{Array, dim4, print, randu, max_ragged};
let vals: [f32; 6] = [1.0f32, 2.0, 3.0, 4.0, 5.0, 6.0];
let rlens: [u32; 2] = [9, 2];
let varr = Array::new(&vals, dim4![3, 2]);
let rarr = Array::new(&rlens, dim4![1, 2]);
print(&varr);



print(&rarr); 

let (out, idx) = max_ragged(&varr, &rarr, 0);
print(&out);

print(&idx);
