[SCIP] best way to use scip with matlab?

[Hans Mittelmann]

Are you talking about QPs or QCPQs? CPLEX can handle non convex QPs and they do not even have 
to be binary. If they are binary they can be linearized or convexified and other solvers can handle them
as well. See my QPLIB benchmarks on http://plato.asu.edu/bench.html <http://plato.asu.edu/bench.html>
However, if you have quadratic constraints you need a global solver.

CPLEX requires the constraint quadratics to be positive semi-definite, so I stumbled on to SCIP after finding the OPTI toolbox. But the OPTI toolbox is apparently only available for Windows, so I figured directly installing scip to run in matlab should be possible, but unlike opti there is no matlab interface, apparently.

I have heard it is possible to access it through ampl, but how would you run scip through the ampl mex?
