WebFinally, there is the more complicated operation of matrix multiplication.The product of two matrices is defined only when the number of columns of the first matrix is the same as the number of rows of the second; in other words, it is only possible to multiply $m \times n$ and $n \times p$ size matrices. The reason for this becomes clear upon defining the product: 1. ^ However, in the case of adjacency matrices, matrix multiplication or a variant of it allows the simultaneous computation of the number of paths between any two vertices, and of the shortest length of a path between two vertices. 2. ^ Lang 2002 3. ^ Fraleigh (1976, p. 209) hana view tableWebSymmetric Matrix.
