[src] Function arrayfire::assign_gen

pub fn assign_gen<T>(lhs: &mut Array<T>, indices: &Indexer<'_>, rhs: &Array<T>) where
  T: HasAfEnum, 

Assign an Array to another after indexing it using any combination of Array's and Sequence's

Examples

use arrayfire::{Array, Dim4, Seq, print, randu, constant, Indexer, assign_gen};
let values: [f32; 3] = [1.0, 2.0, 3.0];
let indices = Array::new(&values, Dim4::new(&[3, 1, 1, 1]));
let seq4gen = Seq::new(0.0, 2.0, 1.0);
let mut a = randu::<f32>(Dim4::new(&[5, 3, 1, 1]));
// [5 3 1 1]
// 0.0000 0.2190 0.3835
// 0.1315 0.0470 0.5194
// 0.7556 0.6789 0.8310
// 0.4587 0.6793 0.0346
// 0.5328 0.9347 0.0535
let b = constant(2.0 as f32, Dim4::new(&[3, 3, 1, 1]));
let mut idxrs = Indexer::default();
idxrs.set_index(&indices, 0, None); // 2nd parameter is indexing dimension
idxrs.set_index(&seq4gen, 1, Some(false)); // 3rd parameter indicates batch operation
assign_gen(&mut a, &idxrs, &b);
println!("a(indices, seq(0, 2, 1))"); print(&a);
// [5 3 1 1]
// 0.0000 0.2190 0.3835
// 2.0000 2.0000 2.0000
// 2.0000 2.0000 2.0000
// 2.0000 2.0000 2.0000
