|  | # Script for explicitly generating template specialization of the | 
|  | # PartitionedMatrixView class. Explicitly generating these | 
|  | # instantiations in separate .cc files breaks the compilation into | 
|  | # separate compilation unit rather than one large cc file. | 
|  | # | 
|  | # This script creates two sets of files. | 
|  | # | 
|  | # 1. partitioned_matrix_view_x_x_x.cc | 
|  | # where the x indicates the template parameters and | 
|  | # | 
|  | # 2. partitioned_matrix_view.cc | 
|  | # | 
|  | # that contains a factory function for instantiating these classes | 
|  | # based on runtime parameters. | 
|  | # | 
|  | # The list of tuples, specializations indicates the set of | 
|  | # specializations that is generated. | 
|  |  |
