How do i plot graphs while varying some constants?for example I would like to plot multiple graphs while varying the velocity on one graph...and i also want to do the same thing with the maximum length and also the times.

Hmax = [.2 .25 .284 .35]; % Maximum length Tmax = [20 40 60 80]; % Maximum time(hrs) u = [.1 .25 .5 1.25];% Advection velocity rhop=10; eps=0.58; kf=1.738*10^(-2); ap=0.95; Ce=1722; Co=[500 1000 1500 1900 2000 2500];
