[PPL-devel] Doxygen bug report: \if does not work (with LaTeX math?)

[Roberto Bagnara]

The attached files exemplify a bug in Doxygen 1.2.11 whereby
the use of \if ... \endif causes the production of wrong LaTeX
output.

To reproduce:

$ doxygen Doxyfile
$ make ps

then see what happens on page 1.

All the best,

    Roberto

Be careful not to confuse the dimension \f$k\f$ of a polyhedron
\f$P \subseteq R^n\f$ with the dimension \f$n\f$ of the enclosing
vector space.

(The following blurb is due to a bug in Doxygen.)

\section homogeneous Homogeneous Systems

To simplify both the constraints and generators 
representations of a polyhedron \f$P \in R^n\f$,
it is useful to map each point \f$\mathbf{x} \in R^n\f$
to a point \f$\mathbf{x}' = (\xi \mathbf{x}, \xi)^T \in R^{n + 1}\f$ 
where \f$\xi \geq 0\f$.
