memmap.flatten(order='C')#

Return a copy of the array collapsed into one dimension.

Parameters:
order{『C』, 『F』, 『A』, 『K』}, optional

『C』 means to flatten in row-major (C-style) order. 『F』 means to flatten in column-major (Fortran- style) order. 『A』 means to flatten in column-major order if a is Fortran contiguous in memory, row-major order otherwise. 『K』 means to flatten a in the order the elements occur in memory. The default is 『C』.

Examples

>>> import numpy as np

>>> a.flatten()
array([1, 2, 3, 4])
>>> a.flatten('F')
array([1, 3, 2, 4])
