numpy.ma.allequal — NumPy v1.13 Manual (original) (raw)
numpy.ma. allequal(a, b, fill_value=True)[source]¶
Return True if all entries of a and b are equal, using fill_value as a truth value where either or both are masked.
| Parameters: | a, b : array_like Input arrays to compare. fill_value : bool, optional Whether masked values in a or b are considered equal (True) or not (False). |
|---|---|
| Returns: | y : bool Returns True if the two arrays are equal within the given tolerance, False otherwise. If either array contains NaN, then False is returned. |
Examples
a = ma.array([1e10, 1e-7, 42.0], mask=[0, 0, 1]) a masked_array(data = [10000000000.0 1e-07 --], mask = [False False True], fill_value=1e+20)
b = array([1e10, 1e-7, -42.0]) b array([ 1.00000000e+10, 1.00000000e-07, -4.20000000e+01]) ma.allequal(a, b, fill_value=False) False ma.allequal(a, b) True
