cells(ZZ,CellComplex) -- return the cells of a cell complex

Synopsis

• Function: cells

• Usage:

  cells(ZZ,C)

• Inputs:
  • r, an integer, the dimension of the cells to be returned
  • C, a cell complex, whose r-cells are to be returned
• Outputs:
  • a list, the r-cells of C

Description

i1 : R = QQ[x,y,z];

i2 : vx = newSimplexCell({},x);

i3 : vy = newSimplexCell({},y);

i4 : vz = newSimplexCell({},z);

i5 : exy = newSimplexCell {vx,vy};

i6 : C = cellComplex(R,{exy,vz});

i7 : cells(0,C)

o7 = {Cell of dimension 0 with label x, Cell of dimension 0 with label z,
     ------------------------------------------------------------------------
     Cell of dimension 0 with label y}
