Standard math textbook notation Scalarsare italic times roman: n, N Vectorsare bold lowercase:x Row vectors are denoted with a transpose:xT Matricesare bold uppercase:M Tensorsare calligraphic letters: TOverview Vectors in R2 Scalar product Outer Product Bases and transformations Inverse Transformations Eigendecomposition Singular Value DecompositionWarm-up: Vectors in Rn We can think of vectors in two ways: Points in a multidimensional space with respect to some coordinate system translation of a point in a multidimensional spaceex.

3 Linear Dependence In R n sets of n+1vectors are always dependent there can be at most n linearly independent vectors Bases (Examples in R2) Bases A basis is a linearly independent set of vectors that spans the “whole space”. ie., we can write every vector in our space as linear combination of vectors in that set.
