//! Writes an Epetra_Vector object to a Matrix Market format file
/*! 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. 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.
\param filename (In) A filename, including path if desired. If a file with this name already exists,

The first column is the global row index, using base 1, the second column is the global

\param handle (In) A C-style file handle, already opened. On exit, the file associated with this handle will
have appended to it a row for each matrix entry
