Hey! How am I supposed to only show the plot with the highest values for h. The graph should show the plot with abs(T1) first and then change to abs(T2) when they intersect and abs(T2) get higher than abs(T1). With the following code I get both plots in all values
plot(h,abs(T1),'b')
hold on
plot(h,abs(T2),'g')
Thanks!

One approach would be ‘logical indexing’:
h = linspace(0,25);
T1 = 20 - h;
T2 = 10 + h;
Lv = abs(T2) > abs(T1); % Logical Index Vector
figure
plot(h,abs(T1),'b', 'LineWidth',2)
hold on
plot(h,abs(T2),'g', 'LineWidth',2)
plot(h(~(Lv)),abs(T1(~Lv)), '--r', 'LineWidth',1.0)
plot(h(Lv),abs(T2(Lv)), '--r', 'LineWidth',1.0)
hold off
Experiment to get the result you want.

plot(h,max(abs(T1),abs(T2)))
