Syntax : numpy.ma.is_masked(arr) Parameters : arr : [array_like] Array to check for masked values. Return : 1 min read numpy.ma.masked_all_like() function | Python numpy.ma.masked_all_like() function return an empty masked array of the same shape and dtype as the array arr, where all the data are masked. Syntax : numpy.ma.masked_all_like(arr) Parameter : arr : [ndarray] An array describing the shape and dtype of the required MaskedArray. Return : [MaskedArray] 1 min read numpy.ma.MaskedArray.count() function - Python numpy.ma.MaskedArray.count() function count the non-masked elements of the array along the given axis. Syntax : numpy.ma.MaskedArray.count(self, axis=None, keepdims = no value) Parameters : axis : [None or int or tuple of ints, optional] Axis along which the count is performed. The default axis is N 2 min read Numpy MaskedArray.cumprod() function | Python numpy.MaskedArray.cumprod() Return the cumulative product of the masked array elements over the given axis.Masked values are set to 1 internally during the computation. However, their position is saved, and the result will be masked at the same locations.

The result may be a view on m1 or m2 if the other is nomask (i.e. False). Syntax : numpy.ma.mask_or(m1, m2, copy = False, shrink = True) Parameters : m1, m2 : [ array_like] Input masks. copy : [bool, optional] If copy is Fal 2 min read numpy.ma.is_mask() function | Python numpy.ma.is_mask() function return True if parameter m is a valid, standard mask. This function does not check the contents of the input, only that the type is MaskType. In particular, this function returns False if the mask has a flexible dtype. Syntax : numpy.ma.is_mask(m) Parameter : m : [array_l 1 min read numpy.ma.masked_values() function | Python numpy.ma.masked_values() function return a MaskedArray, masked where the data in array arr are approximately equal to value, determined using isclose. The default tolerances for masked_values are the same as those for isclose.
