Dataset.
expand_dims
(dim, axis=None)¶ Return a new object with an additional axis (or axes) inserted at the corresponding position in the array shape.
If dim is already a scalar coordinate, it will be promoted to a 1D coordinate consisting of a single value.
Parameters: - dim : str or sequence of str.
Dimensions to include on the new variable. dimensions are inserted with length 1.
- axis : integer, list (or tuple) of integers, or None
Axis position(s) where new axis is to be inserted (position(s) on the result array). If a list (or tuple) of integers is passed, multiple axes are inserted. In this case, dim arguments should be the same length list. If axis=None is passed, all the axes will be inserted to the start of the result array.
Returns: - expanded : same type as caller
This object, but with an additional dimension(s).
