.. py:function:: linear_normalization(matrix, types)

   Normalize decision matrix using linear normalization method.

   Parameters
   -----------
       matrix : ndarray
           Decision matrix with m alternatives in rows and n criteria in columns
       types : ndarray
           Criteria types. Profit criteria are represented by 1 and cost by -1.

   Returns
   --------
       ndarray
           Normalized decision matrix

   Examples
   ----------
   >>> nmatrix = linear_normalization(matrix, types)
