Description

This class simplifies the job of creating matrices from files stored in the Harwell-Boeing format. All matrix types have a constructor that takes a harwell_boeing_stream object. One can also access the elements from a matrix stream using operator>>(). The stream handles both real and complex numbers.

   Usage:
     harwell_boeing_stream mms( fielname );
     Matrix A(mms);
