To compute the differences between consecutive elements of a masked array, use the MaskedArray.ediff1d() method in Python Numpy. The "to_end" parameter sets the number(s) to append at the end of the returned differences.This function is the equivalent of numpy.ediff1d that takes masked values into account, see numpy.ediff1d for details.A masked ...

A new array from the set of choices is constructed using the np.ma.choose() method. The mode parameter is set to 'clip'. If mode='clip', values greater than n-1 are mapped to n-1; and then the new array is constructed.Given an array of integers and a list of n choice arrays, this ... Read More

To return the inner product of two masked arrays with different shapes, use the ma.inner() method in Python Numpy.Ordinary inner product of vectors for 1-D arrays (without complex conjugation), in higher dimensions a sum product over the last axes.The out parameter suggests, if both the arrays are scalars or both ...

To return the inner product of two masked arrays, use the ma.inner() method in Python Numpy. The out parameter suggests, if both the arrays are scalars or both 1-D arrays then a scalar is returned; otherwise an array is returned. out.shape = (*a.shape[:-1], *b.shape[:-1]).A masked array is the combination of ...

To return the dot product of two masked arrays, use the ma.dot() method in Python Numpy. The "strict" parameter sets whether masked data is propagated (True) or set to 0 (False) for the computation.This function is the equivalent of numpy.dot that takes masked values into account. The strict and out ... Read More

To calculate the n-th discrete difference along the given axis, use the MaskedArray.diff() method in Python Numpy. The first difference is given by out[i] = a[i+1] - a[i] along the given axis, higher differences are calculated by using diff recursively −The axis is set using the "axis" parameterThe axis is ...
