Math 355: Linear Algebra

Please let me know if you spot any mistakes in the "new" notes.

First set. This contains geometry of systems linear equations, Gaussian elimination, matrix multiplication, and A = LU factorization.

Second set. This set covers inverses, vector spaces, linear independence, basis, dimension and complete solutions to Ax = b.

Third set. This set covers mostly orthogonality of vectors and subspaces, as well as Gram-Schmidt.

Old notes. This is a big pdf with mostly handwritten notes from teaching the course two years ago. The new notes are/will be much better.
