Default MATLAB - matrice help needed
Matrix M = A=\begin{bmatrix} 1 && 3 \\ -2 && 4 \\ \end{bmatrix} represents a linear transformation T: R^{2} -> R^{2}.
Let u = \begin{bmatrix} 1 \\ -1 \\ \end{bmatrix} and v = \begin{bmatrix} -2 \\ 1 \\ \end{bmatrix}
(a) Find T(u) and T(v)
(b) Show that T (u + v) = T (u) + T (v).

I'm pretty hopeless at Matlab. I can work these out by hand: eg T(u) = \begin{bmatrix} -2 \\ -6 \\ \end{bmatrix} (correct?) but what commands do I use in Matlab to get this?
