Macro extendr_api::prelude::stack_new_axis
source ยท macro_rules! stack_new_axis { ($axis:expr, $( $array:expr ),+ ) => { ... }; }
๐Deprecated since 0.15.0: Use under the name stack instead.
Expand description
Stack arrays along the new axis.
Uses the stack_new_axis()
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_new_axis, Axis};
let a = arr2(&[[2., 2.],
[3., 3.]]);
assert!(
stack_new_axis![Axis(0), a, a]
== arr3(&[[[2., 2.],
[3., 3.]],
[[2., 2.],
[3., 3.]]])
);
