To pickle the masked array, use the ma.MaskedArray.dumps() method. Load the pickle back to array using the pickle.loads() method in Numpy. 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.NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. It supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, ... Read More

To return a copy of the masked array, use the ma.MaskedArray.copy() method in Python Numpy. The order parameter controls the memory layout of the copy. ‘C’ means C-order, ‘F’ means F-order, ‘A’ means ‘F’ if a is Fortran contiguous, ‘C’ otherwise. ‘K’ means match the layout of a as closely as possible. (Note that this function and numpy.copy are very similar but have different default values for their order = arguments, and this function always passes sub-classes through.)StepsAt first, import the required library −import numpy as np import numpy.ma as maCreate an array with int elements using the numpy.array() method ...

To compute the median of the masked array elements, use the MaskedArray.median() method in Python Numpy.The overwrite_input parameter, if True, then allow use of memory of input array (a) for calculations. The input array will be modified by the call to median. This will save memory when you do not need to preserve the contents of the input array. Treat the input as undefined, but it will probably be fully or partially sorted. Default is False. Note that, if overwrite_input is True, and the input is not already an ndarray, an error will be raised.StepsAt first, import the required library ... Read More
To return the average of the masked array elements, use the MaskedArray.average() method in Python Numpy. The "axis" parameter is used to axis along which to average the array. If None, averaging is done over the flattened array.The weights parameter suggests the importance that each element has in the computation of the average. The weights array can either be 1-D or of the same shape as a. If weights=None, then all data in a are assumed to have a weight equal to one. The 1-D calculation is −avg = sum(a * weights) / sum(weights)The function returns the average along the ... Read More

To return the default fill value for an array with complex datatype, use the ma.default_fill_value() method in Python Numpy. The default filling value depends on the datatype of the input array or the type of the input scalar −datatypeDefaultboolTrueint999999float1.e20complex1.e20+0jobject'?'string'N/A'For structured types, a structured scalar is returned, with each field the default fill value for its type. For subarray types, the fill value is an array of the same size containing the default scalar fill value.StepsAt first, import the required library −import numpy as np import numpy.ma as maCreate an array with complex type elements using the numpy.array() method −arr = ...
