dim(Cell) -- compute the dimension of a cell

Synopsis

Function: dim
Usage:

dim C
Inputs:
- C, a cell, the cell to compute the dimension of
Outputs:
- an integer, the dimension of the cell

Description

Given a cell C, dim returns its dimension. In general the dimension of the cell is inferred from the dimension of its boundary. However, this can be overridden if the cell is created using newCell with the CellDimension option.

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 : dim(vz)

o7 = 0

i8 : dim(exy)

o8 = 1
