Adjacency Matrix

An adjacency matrix is a way to represent connections between items in a structured format, often used in graph theory. Imagine a grid where both rows and columns represent the same set of items, like cities. If two items are connected, you place a "1" in the cell where their row and column intersect; if not, you place a "0". This matrix helps visualize relationships and can be useful for analyzing networks, such as social connections or transportation routes, allowing us to see at a glance which items are linked directly to others in the system.
