Thank you for the clarification!

cell complexes do not support ranks beyond 2. The incidence matrix in a cell complex takes a single parameter, as it is supposed to be the linear rep of the boundary map in algebraic topology.

For instance CC.incidence_matrix(1) of a cell complex CC computes the incidence between 0 and 1 rank cells (nodes and edges). incidence_matrix(2) computes between edges and faces (rank 2 cells).

If you want to go for node and face incidence then you are looking for set-based incidence which is supported in combinatorial complex or colored hypergraph. In that case when you need to compute the incidence between rank i and rank j you pass use : incidence_matrix(i,j). Hope that helps.
