As a simple tool for understanding complex things, matrix has been widely used in various disciplines and mathematical modeling. The development of any discipline is closely related to quantitative analysis and research, and mathematics plays a vital role in quantitative research. Matrix is one of the most basic mathematical concepts, and it is also a simple thinking tool for people to grasp the essence of complex practical things. Matrix is widely used in mathematical modeling. In the process of mathematical modeling, we often encounter some mathematical models that can be handled by graphs and adjacency matrices of graphs. Using adjacency matrix to represent graphs is simple and intuitive, and adjacency matrix can represent some practical information of graphs. In this paper, the application of adjacency matrix in mathematical modeling is analyzed and studied, and on this basis, the application of matrix in mathematical modeling is further studied and popularized.
