      to the specified file.  The matrix can be distributed or serial.  The user can provide
      a strings containing the matrix name, a matrix description, and specify that header information
      should or should not be printed to the file.

      \param filename (In) A filename, including path if desired.  If a file with this name already exists,
                      it will be deleted.  On exit, this file will contained any requested header information
		      followed by the matrix coefficients.  The file will contain a row for each matrix entry
		      The first column is the global row index, using base 1, the second column is the global
		      column index of the entry, the third value is the matrix value for that entry.
      \param A (In) An Epetra_Vector Object containing the user matrix to be dumped to file.  Any object
                    that implements the Epetra_Vector interface can be passed in.  In particular, the 
		    Epetra_CrsMatrix, Epetra_VbrMatrix, Epetra_FECrsMatrix, Epetra_FEVbrMatrix and Epetra_MsrMatrix
		    classes are compatible with this interface.
      \param matrixName (In) A C-style string pointer to a name that will be stored in the comment field of the file.
                         This is not a required argument.  Note that it is possible to pass in the method A.Label() if 
			 the matrix is one of the four types: Epetra_CrsMatrix, Epetra_VbrMatrix, Epetra_FECrsMatrix, 
			 Epetra_FEVbrMatrix.
      \param matrixDescription (In) A C-style string pointer to a matrix description that will be stored in the comment 
                                    field of the file.
      \param writeHeader (In) If true, the header will be written, otherwise only the matrix entries will be written.

      \return Returns 0 if no error, -1 if any problems with file system.

  /*! This function takes any matrix that implements the Epetra_Vector interface and writes it
      to the specified file.  The matrix can be distributed or serial.  This function is a convenience wrapper 
      around VectorToMatrixMarketFile.  The following Matlab commands can be used to read the resulting file
      and convert to it to a Matlab sparse matrix:
      <ol>
      <li> load \e filename;
      <li> matrix_name = spconvert(filename_root);
      </ol>
      For example:
      <ol>
      <li> load A.dat;
      <li> A = spconvert(filename_root);
      </ol>
      The above produces a sparse matrix A.
