Macro surge_wavetable::imports::imports::stack

macro_rules! stack {
    ($axis : expr, $($array : expr), +) => { ... };
}

Stack arrays along the new axis.

Uses the stack function, calling ArrayView::from(&a) on each argument a.

Panics if the stack function would return an error.

extern crate ndarray;

use ndarray::{arr2, arr3, stack, Axis};


let a = arr2(&[[2., 2.],
               [3., 3.]]);
assert!(
    stack![Axis(0), a, a]
    == arr3(&[[[2., 2.],
               [3., 3.]],
              [[2., 2.],
               [3., 3.]]])
