Matrix multiplication: if A is a matrix of size m n and B is a matrix of size n p, then the product AB is a matrix of size m p. Vectors: a vector of length n can be treated as a matrix of size n 1, and the operations of vector addition, multiplication by scalars, and multiplying a matrix by a vector agree with the corresponding matrix operations.
