How to find the time for the max height of the rocket. MATLAB

Hi there! Doing a little final practice and was asked to find the max height and the time of the max height of the rocket. I can't figure out the code for the time.

function rocket
g=9.81;
vi=50;
yi=0;
theta=(pi/3);
t=0:0.1:12;
x=vi*cos(theta)*t;
y=yi+vi*sin(theta)*t-((1/2)*g*(t.^2));
plot(t,y)

Maxheight=max([y(:)])

end

Answer 1

[Maxheight, timeindex] = max(y);

Now timeindex tells you which entry in y was maximum, and you can use that index to figure out what the corresponding time was.

how to find the corresponding time was.

[Walter Roberson]

t(timeindex)

See my attached demo for a projectile, which computes just about everything you could possibly think to measure.
