Session Overview

Figure excerpted from 'Introduction to Linear Algebra' by G.S. Strang

After a final discussion of positive definite matrices, we learn about “similar” matrices: B = M−1AM for some invertible matrix M. Square matrices can be grouped by similarity, and each group has a “nicest” representative in Jordan normal form. This form tells at a glance the eigenvalues and the number of eigenvectors.
