Member Function Documentation

virtual void SparseSymMatrix::writefToStream (  std::ostream &    out, const char    format[] )  const [virtual]

Write the components of this OOQP_Matrix to a stream, subject to a format. Parameters: out  a C++-style output stream format  a string used to format the output with respect to mH. The substrings %{irow} and %{jcol} will be substituted by the index of the current element and the string %{value} will be substituted with the element's value. // Example H->writefToStream( cout, "H[%{irow}, %{jcol}] = %{value}" ); Implements SymMatrix.
