Source 
pub fn diff2<T>(input: &Array<T>, dim: i32) -> Array<T::InType>
where
    T: HasAfEnum,
    T::InType: HasAfEnum,
Expand description

Calculate second order numerical difference along a given dimension

§Parameters

  • input - Input Array
  • dim - Dimension along which second order difference is calculated

§Return Values

Result Array with second order difference values

§Examples

use arrayfire::{Dim4, print, randu, diff2};
let dims = Dim4::new(&[5, 3, 1, 1]);
let a = randu::<f32>(dims);
print(&a);
let b = diff2(&a, 0);
print(&b);
let c = diff2(&a, 1);
print(&c);
