numpy.matlib.empty() — another function to do matrix operations in numpy. It returns a new matrix of the given shape and type without initializing records.

Syntax: numpy.matlib.empty (shape, dtype = None, order = `C`)

Parameters:
shape: [int or tuple of int] Shape of the desired output empty matrix.
dtype: [optional] Desired output data-type.
order: Whether to store multi-dimensional data in row-major (C-style) or column-major (Fortran -style) order in memory.

Return: A new matrix of given shape and type,
