boundary(SimplicialComplex) -- the boundary simplicial complex of D

Synopsis

Description

loadPackage "SimplicialComplexes";
The boundary of the standard 3-simplex is the 2-sphere.
R = ZZ[a..d];
simplex = simplicialComplex{a*b*c*d}
sphere = boundary simplex
fVector sphere
fVector simplex
Facets may be of different dimensions.
R = ZZ[a..g];
D = simplicialComplex{a*b*c,a*d,d*f,g*c,e,f*g}
E = boundary D
fVector D
fVector E
