Vectors and Matrices: Vectors are ordered N-­‐tuples of numbers dot-­‐ or inner-­‐product (scalar) norm (or generalized length) matrix is a square N x N array Unit Matrix Multiplication of a vector by a matrix on the left gives a new vector the product of two matrices is a matrix The transpose of a matrix is given by
