function [nnps,nnodes,nres,nbn]=nodenums(N)
% [nnps,nnodes,nres,nbn]=nodenums(N)
% calculate the number of nodes per side, number of nodes, number of resistors
% number of boundary nodes

nnps = N+1;        % number of nodes per side
nnodes = nnps^2;   % number of nodes
nres = 2*N*(N+1);  % number of resistors
nbn = 4*N;         % number of boundary nodes
