MAT 211 Introduction to Linear Algebra, Spring 2015

-- This course will focus mainly on computations (rather than on mathematical proofs). Some of the topics we will cover are: vectors in n-space; matrices and the algebra of matrices; abstract vector spaces and subspaces; linear transformations and operators – and their kernels and images; basis for a vector space and dimension; eigenvalues and eigenvectors; diagonalization of linear operators.
