matrix.byteswap()

matrix.byteswap(inplace)

Swap the bytes of the array elements

Toggle between low-endian and big-endian data representation by returning a byteswapped array, optionally swapped in-place.

Parameters:

Parameters:	inplace : bool, optional If `True`, swap bytes in-place, default is `False`.
Returns:	out : ndarray The byteswapped array. If `inplace` is `True`, this is a view to self.

inplace : bool, optional

If True, swap bytes in-place, default is False.

Returns:

out : ndarray

The byteswapped array. If inplace is True, this is a view to self.

Examples

>>> A = np.array([1, 256, 8755], dtype=np.int16)
>>> map(hex, A)
['0x1', '0x100', '0x2233']
>>> A.byteswap(True)
array([  256,     1, 13090], dtype=int16)
>>> map(hex, A)
['0x100', '0x1', '0x3322']

Arrays of strings are not swapped

>>> A = np.array(['ceg', 'fac'])
>>> A.byteswap()
array(['ceg', 'fac'],
      dtype='|S3')
