ArrayTrait - Array Count functions

Required Methods§

source

fn count_nonzero( &self, axis: Option<isize>, keepdims: Option<bool> ) -> Result<Array<usize>, ArrayError>

Sort an array

Arguments
  • axis - axis along which to count. if None, array is flattened
  • keepdims - if true, the result will broadcast correctly against the input
Examples
use arr_rs::prelude::*;

let arr: Result<Array<i32>, ArrayError> = array_eye!(4);
assert_eq!(array!([4]), arr.count_nonzero(None, None));

let arr: Result<Array<i32>, ArrayError> = array!([[0, 1, 7, 0], [3, 0, 2, 19]]);
assert_eq!(array!([1, 1, 2, 1]), arr.count_nonzero(Some(0), None));
