colour.utilities.interval#

colour.utilities.interval(distribution: ArrayLike, unique: bool = True) → NDArray[source]#

Return the interval size of the specified distribution.

Parameters:

distribution (ArrayLike) – Distribution to retrieve the interval from.
unique (bool) – Whether to return unique intervals if the distribution is non-uniformly spaced or the complete intervals.

Returns:

Distribution interval.

Return type:

numpy.ndarray

Examples

Uniformly spaced variable:

>>> y = np.array([1, 2, 3, 4, 5])
>>> interval(y)
array([ 1.])
>>> interval(y, False)
array([ 1.,  1.,  1.,  1.])

Non-uniformly spaced variable:

>>> y = np.array([1, 2, 3, 4, 8])
>>> interval(y)
array([ 1.,  4.])
>>> interval(y, False)
array([ 1.,  1.,  1.,  4.])
