Graphical Operators

Description

These operators allow for algebraic manupulation of graph adjacency matrices.

Usage

## S3 method for class 'matrix'
e1 %c% e2

Arguments

`e1`	an (unvalued) adjacency matrix.
`e2`	another (unvalued) adjacency matrix.

Details

Currently, only one operator is supported. x %c% y returns the adjacency matrix of the composition of graphs with adjacency matrices x and y (respectively). (Note that this may contain loops.)

Value

The resulting adjacency matrix.
