Function stack 

Source
pub fn stack<A, D>(
    axis: Axis,
    arrays: &[ArrayBase<ViewRepr<&A>, D>],
) -> Result<ArrayBase<OwnedRepr<A>, <D as Dimension>::Larger>, ShapeError>
where A: Clone, D: Dimension, <D as Dimension>::Larger: RemoveAxis,
Expand description

Re-export essential macros that were missing in some modules Stack arrays along the new axis.

Errors if the arrays have mismatching shapes. Errors if arrays is empty, if axis is out of bounds, if the result is larger than is possible to represent.

               [3., 3.]]);
