[SCIP] best way to use scip with matlab?

[Stefan Vigerske]

Hi,

the .lp format is quite easy to write and also understood by a number of 
other solvers. The .pip format is similar and a bit simpler, but 
understood by hardly any solver (other than SCIP), as far as I know.
To use the AMPL SCIP interface, you might need an AMPL license, or write 
.nl files directly.

There is also a matlab interface distributed with SCIP (see 
interfaces/matlab), but I don't know its current status.
