I is another operation  ill review matrix operation on graphs. When we represent graphs as matrices, we can now use mathematics and software tools to find patterns. This is easier than visually analyzing a complicated graph. The matrix representations are usually square but they can be three dimensional also consisting of rows columns and levels or slices. Matrices can also be symmetric or unsymmetric. In symmetric matrix the value in row I column t is the same as row t column I. As an example of an unsymmetric matrix, consider social relations where jack may have a liking for Jill but Jill may not have a liking for Jack.
Operations permitted on a matrix include the following
Permutation here the rows and columns are rearranged such as in a symmetric matrix to find patterns. With these reorderings, the pairwise relationships are not affected.
Partitioning is another operation where the matrix is split into blocks or images.
Embedding is another operation that helps finds groups of nodes that participate in different patterns
