- a vector space is a set whose elements conform to the eight axioms of scaling and additiveness
|
||||
- e.g.,
|
||||
- ℝ², ℝ³, P₃
|
||||
- In this course we focus on three main vector spaces
|
||||
- ℝⁿ, Pₙ, $M_{m\times n}$
|
||||
|
||||
- a vector subspace is a subset of a vector space whose elements (which are vectors) are additively and multipicatively closed and contain the zero vector
