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 ofa
as closely as possible. (Note that this function andnumpy.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
