Member Function Documentation

◆ append_row()

template<typename It >

RowIndex smtrat::fmplex::Matrix::append_row	(	const It &	begin,
		const It &	end
	)

inline

Appends the row contained in the range between begin and end to the matrix.

This assumes the inputs to be of the same iterator-like type pointing to RowEntry's.

Returns: the row index of the appended row within the matrix.
