# numpy.matlib.empty

matlib.empty(shape, dtype=None, order='C')

  Return a new matrix of given shape and type, without initializing entries.

  Parameters:
    shape int or tuple of int

      Shape of the empty matrix.

    dtype data-type, optional

      Desired output data-type.

    order{‘C’, ‘F’}, optional

      Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran-style) order in memory.

  Notes

  `empty`, unlike `zeros`, does not set the matrix values to zero, and may therefore be marginally faster. On the other hand, it requires the user to manually set all the values in the array, and should be used with caution.

  Examples

      >>> import numpy.matlib
      >>> np.matlib.empty((2, 2))    # filled with random data
      matrix([[  6.76425276e-320,   9.79033856e-307], # random
              [  7.39337286e-309,   3.22135945e-309]])
      >>> np.matlib.empty((2, 2), dtype=int)
      matrix([[ 6600475,        0], # random
              [ 6586976, 22740995]])
