# numpy.matrix.tostring

`matrix.``tostring`(order='C')

  Construct a Python string containing the raw data bytes in the array.

  Constructs a Python string showing a copy of the raw contents of data memory. The string can be produced in either ‘C’ or ‘Fortran’, or ‘Any’ order (the default is ‘C’-order). ‘Any’ order means C-order unless the F_CONTIGUOUS flag in the array is set, in which case it means ‘Fortran’ order.

  Parameters : | order : {‘C’, ‘F’, None}, optional Order of the data for multidimensional arrays: C, Fortran, or the same as for the original array.
  Returns : | s : str A Python string exhibiting a copy of a‘s raw data.

  Examples

      >>> x = np.array([[0, 1], [2, 3]])
      >>> x.tostring()
      '\x00\x00\x00\x00\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00'
      >>> x.tostring('C') == x.tostring()
      True
      >>> x.tostring('F')
      '\x00\x00\x00\x00\x02\x00\x00\x00\x01\x00\x00\x00\x03\x00\x00\x00'
