Description:
 def copy(self, order="C"):
 """ 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 :func:`numpy.copy` are very similar, but have different default values for their order= arguments.) See also -------- numpy.copy numpy.copyto Examples -------- [[0 0 0] [0 0 0]] km [[1 2 3] [4 5 6]] km """
