I am learning matlab and trying to plot vectors. I defined V=[3;4] to represent 3x^+4y^ and attempt to display using plot(V) hoping to see a vector from origin to (3,4) but instead the graph shows a vector from (1,3) to (2,4). Is it a problem with my plotting settings or am I not using the correct script?

% or
quiver(0, 0, 3, 4)
