Macro tract_pulse::internal::tract_core::ops::nn::tract_ndarray::stack_new_axis

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

👎Deprecated since 0.15.0: Use under the name stack instead.

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;

let a = arr2(&[[2., 2.],
               [3., 3.]]);

    stack_new_axis![Axis(0), a, a]
    == arr3(&[[[2., 2.],
               [3., 3.]],
              [[2., 2.],
               [3., 3.]]])
