Linear mappings - definition by the images of the coordinate unit vectors

It is sufficent to specify the images of the unit vectors. You can set the vectors \(\varphi(e_1)\) and \(\varphi(e_2)\) by dragging them around.

\(\varphi(\mathbf{v})= Av = v_1 \mathbf{a}_1+v_1 \mathbf{a}_1 = v_1 \varphi(e_1)+ v_2 \varphi(e_2)\)
