Linear Algebra — Matrices

Transpose & symmetry

continues from lesson 3 — values defined earlier in the course stay live here

Mt=transpose(M)M_{t} = \mathrm{transpose}\left(M\right) = [[2,1],[1,3]][[2, 1], [1, 3]] flip across the diagonal
✓ pass det(Mt)==dMdet(M_{t}) == d_{M} transposing never changes the determinant

Where next: Differential Equations — where matrices and calculus join forces to describe anything that evolves.
