pdim -- calculate the projective dimension

Synopsis

Usage:

pdim M

Caveat

For now, the method is to measure the length of a projective resolution.

Ways to use pdim :

pdim(BettiTally) -- see BettiTally -- the class of all Betti tallies
pdim(CoherentSheaf) -- calculate the projective dimension
pdim(Module) -- calculate the projective dimension of a module

For the programmer

The object pdim is a method function.
