2.2: Matrix multiplication and linear combinations

Let the field K be the set R of real numbers, and let the vector space V be the Euclidean space R . Consider the vectors e1 = (1,0,0), e2 = (0,1,0) and e3 = (0,0,1). Then any vector in R is a linear combination of e1, e2, and e3. To see that this is so, take an arbitrary vector (a1,a2,a3) in R , and write: Let K be the set C of all complex numbers, and let V be the set CC(R) of all continuous functions from … Nettet26. mai 2024 · So as per the definition of vectors, the vector$\begin{bmatrix}1\\1\end{bmatrix}$ is 1 unit away from i and 1 unit away from j. After the transformation, it will be at $\begin{bmatrix}2\\3\end{bmatrix}$ The matrix vector multiplication when expressed as such a linear combination, is very intuitive.
