Description

This class simplifies the job of creating matrices from files stored in the Matrix Market format. All matrix types have a constructor that takes a matrix_market_stream object. One can also access the elements (of type entry2) from a matrix stream using the stream operator. The stream handles both real and complex numbers.

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