# numpy.matrix.byteswap

method

matrix.byteswap(inplace=False)

  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. Arrays of byte-strings are not swapped. The real and imaginary parts of a complex number are swapped individually.

  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.

  Examples

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

  Arrays of byte-strings are not swapped

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

  `A.newbyteorder().byteswap()` produces an array with the same values

    but different representation in memory

      >>> A = np.array([1, 2, 3])
      >>> A.view(np.uint8)
      array([1, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 3, 0, 0, 0, 0, 0,
             0, 0], dtype=uint8)
      >>> A.newbyteorder().byteswap(inplace=True)
      array([1, 2, 3])
      >>> A.view(np.uint8)
      array([0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0,
             0, 3], dtype=uint8)
