Use quiver to change points into vectors?

If I use rand(n) to create a matrix of random numbers, can I use quiver to plot them as random vector arrows? Or do I need to use something else?
I want to be able to generate random values then plot them as vectors which can be later used to generate a new graph that will be based on the random vectors.

I could answer this if the n in rand(n) is either 2 or 3. If it's more than 3, I'm afraid 4 dimensional vector visualization is beyond the scope of our imagination, almost!
This may help:
function [] = visualizerndvect(numofvectors, dimension)
if dimension <= 3 Data = rand(numofvectors,dimension); if dimension == 2 figure, quiver(zeros(size(Data,1),1),zeros(size(Data,1),1),Data(:,1),Data(:,2)); else if dimension == 3 figure, quiver3(zeros(size(Data,1),1),zeros(size(Data,1),1),zeros(size(Data,1),1),Data(:,1),Data(:,2),Data(:,3)) end end else fprintf('Dimension beyond visualization capacity!\n'); end
Thanks!
