adjacency.matrix {copCAR} | R Documentation |
Return an adjacency matrix for a square lattice.
adjacency.matrix(m, n = NULL)
m |
the number of rows in the lattice. |
n |
the number of columns in the lattice. Defaults to |
This function builds the adjacency matrix for the m
by n
square lattice.
A matrix A
of 0s and 1s, where A_{ij}
is equal to 1 iff vertices i
and j
are adjacent.
