numpy.ma.copy

numpy.ma.copy(self, *args, **params) a.copy(order='C') = <numpy.ma.core._frommethod object>

Return a copy of the array.

Parameters

order{‘C’, ‘F’, ‘A’, ‘K’}, optional

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.)

Examples

>>>

>>> x = np.array([[1,2,3],[4,5,6]], order='F')

>>>

>>> y = x.copy()

>>>

>>> x.fill(0)

>>>

>>> x
array([[0, 0, 0],
       [0, 0, 0]])

>>>

>>> y
array([[1, 2, 3],
       [4, 5, 6]])

>>>

>>> y.flags['C_CONTIGUOUS']
True
