Hi I have to plot the speed of a Basejumper in dependence of the time. For this I'm using a while loop with the plot command underneath. That's my code:
while s>0% a=g+k/m*v.^2; deltav=a*deltat; v=v+deltav deltas=v*deltat; s=s+deltas; t=t+deltat; end plot(t,v) hold on
sprintf('Der Flug dauerte %5.3f Sekunden',t) sprintf('Die Geschwindigkeit beim Aufschlag betrug %5.3f m/s',v)
Unfortunately Matlab shows only one point in the diagram not the whole graph. Does anybody knows what I did wrong?
You overwrite t,v on each iteration of the for-loop. Instead you need to either plot them then or store them to plot later.
count = 0; while ... count = count+1; v(count) = v(count-1)+deltav; end
or plot as you're going;
hold on while ... %stuff plot(t,v) end
