The undervalued linear algebra fact: matrices are graphs and multiplication transforms networks
TivadarDanka · x · 2026-09-22
Math writer Tivadar Danka shares what he calls the single most undervalued fact of linear algebra: stop thinking of a matrix as just a grid of floating-point numbers.
- Matrices are graphs and graphs are matrices: every matrix multiplication is a network transformation where nodes pass signals along weighted edges.
- Shifting from mechanical arithmetic to the graph intuition transforms linear algebra from boring to beautiful—a view closely related to the ideas behind modern models like GNNs.
