cupy.atleast_3d¶

cupy.atleast_3d(*arys)[source]¶

Converts arrays to arrays with dimensions >= 3.

If an input array has dimensions less than three, then this function inserts new axes to make it have three dimensions. The place of the new axes are following:

If its shape is (), then the shape of output is (1, 1, 1).
If its shape is (N,), then the shape of output is (1, N, 1).
If its shape is (M, N), then the shape of output is (M, N, 1).
Otherwise, the output is the input array itself.

Parameters:	arys (tuple of arrays) – Arrays to be converted. All arguments must be `cupy.ndarray` objects.
Returns:	If there are only one input, then it returns its converted version. Otherwise, it returns a list of converted arrays.
