Re: Plotting vectors as points

[Sue Stones]

I fianally managed to solve the problem, I worked out how to plot points using 
numbers only, and ony after giving up have found the info to let me plot the 
points directly, by taking the vetor apart like a matrix. 

p1 = [1; 4];            % vector p1
plot(p1(1,:), p1(2,:), '@b*');

I still can't believe its such an unusual thing to do, but at least I've done 
it.  Or is it so obvious that there is no need to mention it in the 
tutorials??? (At least anyone reading through this list or the archives, will 
have a chance of learning from my problems).

Now I need to see if I can determine the format string with a variable.  Does 
anyone know if this is possible.
