Frobby is a software system and project for computations with monomial ideals. Frobby is free software and it is intended as a vehicle for research on monomial ideals, as well as a useful practical tool for investigating monomial ideals.
Available functions:
long dimension(const ideal& I);
ideal AlexanderDualFrobby(I, pp);
ideal AlexanderDualFrobby(I);
ideal MaximalStandardMonomialsFrobby(I);
void IrreducibleDecompositionFrobby(std::vector<ideal>& components, I);
void PrimaryDecompositionFrobby(std::vector<ideal>& components, I);
void AssociatedPrimesFrobby(std::vector<ideal>& primes, I);
RingElem MultigradedHilbertPoincareNumeratorFrobby(I);
RingElem TotalDegreeHilbertPoincareNumeratorFrobby(I);
RingElem TotalDegreeHilbertPoincareNumeratorFrobby(I, const RingElem& base);

CoCoALib requires Frobby release 0.9.0 or later. Download Frobby from the website.
IMPORTANT there are some minor mistakes in the frobby source code:
main.cpp and randomDataGenerators.cpp
#include <sys/types.h>
#include <unistd.h>
StatisticsStrategy.cpp change mpz_class into mpq_class
Now compile Frobby following the instructions in the Frobby release.
NOTE: JAA says that to compile Frobby (0.8.2) on my machine I had to
execute the following:
export CFLAGS="-m64 -mtune=core2 -march=core2" # taken from gmp.h export LDFLAGS=$CFLAGS make library
make might give some linking issues if libgmpxx is not installed
systemwide. Anyway, for linking with CoCoA you only need make library.
Look to see where the library file libfrobby.a is -- on my computer
it was inside the Frobby subdirectory bin/. Note the full path to
the library file as you will need it when configuring CoCoALib!
Then configure and compile CoCoALib typing
cd CoCoALib-0.99 ./configure --with-libfrobby=<your_path_to>/libfrobby.a make
Currently Frobby is not really intended to be used as a library, so linking it with CoCoALib is not as simple as it could be. Hopefully this will soon change.
