pub fn stack_fn<A, D>(
axis: Axis,
arrays: &[ArrayBase<ViewRepr<&A>, D>],
) -> Result<ArrayBase<OwnedRepr<A>, <D as Dimension>::Larger>, ShapeError>
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.
