colour.utilities.in_array

colour.utilities.in_array(a: ArrayLike, b: ArrayLike, tolerance: Real = EPSILON) → NDArray

Determine whether each element of array \(a\) is present in array \(b\) within the specified tolerance.

Parameters:

• a (ArrayLike) – Array \(a\) to test the elements from.

• b (ArrayLike) – Array \(b\) against which to test the elements of array \(a\).

• tolerance (Real) – Tolerance value.

Returns:

Boolean array with array \(a\) shape indicating whether each element of array \(a\) is present in array \(b\) within the specified tolerance.

Return type:

numpy.ndarray

>>> a = np.array([0.50, 0.60])
>>> b = np.linspace(0, 10, 101)
>>> np.isin(a, b)
