How to create an adjacency matrix of a directed graph? 1. Dijkstra's Algorithm c++. 2. WebAn adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. Adjacent means 'next to or adjoining something else' or to be beside something. For example, your neighbors are adjacent to you. In graph theory, if we can go to node B from ...
