Why is my code only outputting one value instead of a vector?

v_0=input('Enter the inital Velocity');

g=input('Enter Gravity Constant');

for t=0:0.05:(pi/2)

r=(v_0^2/g)*sin(2*t)%#ok<NOPTS>

end

I am newer to matlab so I am unsure of why this is happening.

That is because you did not index ‘r’.

Either do this (without the loop):

t=0:0.05:(pi/2)
r=(v_0^2/g)*sin(2*t);%#ok<NOPTS>

or this (with the loop):

t=0:0.05:(pi/2);
for k = 1:numel(t)
    r(k)=(v_0^2/g)*sin(2*t(k))%#ok<NOPTS>
end

Both will work, and both will produce the required result.

Thanks that was the result i was looking for!
