Chapter 6: Matrices and Determinants
Why This Matters
Matrices are the language of linear transformations. They encode:
-
Rotations, reflections, and scaling in graphics
-
Networks of connections in graphs
-
Systems of equations in compact form
-
State transitions in Markov chains
When you multiply a matrix by a vector, you’re transforming space itself.
