numpy.ma.zeros

numpy.ma.zeros(shape, dtype=float, order='C') = <numpy.ma.core._convert2ma object>

Return a new array of given shape and type, filled with zeros.

Parameters:	shape : int or tuple of ints Shape of the new array, e.g., (2, 3) or 2. dtype : data-type, optional The desired data-type for the array, e.g., numpy.int8. Default is numpy.float64. order : {‘C’, ‘F’}, optional, default: ‘C’ Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory.
Returns:	out : ndarray Array of zeros with the given shape, dtype, and order.

array([[ 0.],
       [ 0.]])

>>> s = (2,2)
>>> np.zeros(s)
array([[ 0.,  0.],
       [ 0.,  0.]])

>>> np.zeros((2,), dtype=[('x', 'i4'), ('y', 'i4')]) # custom dtype
