Create a masked array using the ma.MaskedArray() method. The mask is set using the "mask" parameter. Set to False here. The datatype is set using the "dtype" parameter. The fill_value parameter is used to fill in the masked values when necessary. A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.StepsAt first, import the required library −import numpy as np import ...

The mask is initialized to homogeneous boolean array with the same shape as data by passing in a scalar boolean value. True indicates a masked (i.e. invalid) data.

To count the non-masked elements of the masked array along axis 1, use the ma.MaskedArray.count() method in Python Numpy. The axis is set using the "axis" parameter. The method returns an array with the same shape as the input array, with the specified axis removed. If the array is a 0-d array, or if axis is None, a scalar is returned.The axis parameter is the axis or axes along which the count is performed. The default, None, performs the count over all the dimensions of the input array. axis may be negative, in which case it counts from the last ... Read More
To count the non-masked elements of the masked array along axis 0, use the ma.MaskedArray.count() method in Python Numpy. The axis is set using the "axis" parameter. .

To return the maximum value that can be represented by the dtype of an object, use the ma.minimum_fill_value() method in Python Numpy. This function is useful for calculating a fill value suitable for taking the minimum of an array with a given dtype. It returns the maximum representable value.A masked array is the combination of a standard numpy.ndarray and a mask.
