Find the time when a parabolic function starts to decrease.

Hello,
My task is to write a script that will find the time when a parabolic function (height, a function of time) reaches its max.
clear all
t=0;
for time=0:0.5:30;
if height(time)>=height(time-0.5)
t=t+0.5;
end
end
disp(t)
height(time-0.5) wouldn't execute so here is my second code
clear all
t=0;
for time=0:0.5:30;
e=0.5:0.5:29;
time2=[0 e];
while height(time)>height(time2)
t=t+0.5;
end
end
disp(t)
this code does not work either. How can i utilize max( ) function in here? And what is the best way to do this kind of loop?
Thanks!

What is height here? If it is a vector then you cannot use height(time) you can only use height(SomePositiveIntegerIndex) . But once you have found the appropriate positive integer index, you can use it to figure out what the corresponding time is.

[maxheight, idx] = max(height(time))
where time is a vector. Then time(idx)
