ones

Return a SparseArray of given shape and type, filled with ones.

Parameters:

Name	Type	Description	Default
shape	int or tuple of ints	Shape of the new array, e.g., (2, 3) or 2.	required
dtype	data - type	The desired data-type for the array, e.g., numpy.int8. Default is numpy.float64.	float
format	str	A format string.	'coo'
compressed_axes	iterable	The axes to compress if returning a GCXS array.	required

Returns:

Name	Type	Description
out	SparseArray	Array of ones with the given shape and dtype.

Examples:

>>> ones(5).todense()
array([1., 1., 1., 1., 1.])

>>> ones((2, 2), dtype=int).todense()
array([[1, 1],
       [1, 1]])
