MATLAB: How to add equation to function

forfor loopfunction

I need to add my equation (60+(2.13*(t^2))-(0.0013*(t^4))+(0.000034*(t^4.751))) to a function but I cant figure it out. What I've tried just comes out as an error. Please help.
k=1;
for t = 0:2:100;
    h(k) = (60+(2.13*(t^2))-(0.0013*(t^4))+(0.000034*(t^4.751)));
    k = k+1;
    if h>=0
       disp(h);      
    end 
end
This is what I tried but it doesnt work.
k=1;
for t = 0:2:100;
    h(k) = rocket(t)
    k = k+1;
    if h>=0
       disp(h);      
    end 
end
function h(k) = rocket(t)
    h(k) = (60+(2.13*(t^2))-(0.0013*(t^4))+(0.000034*(t^4.751)));
end

Note: the following can be done trivially without a loop by vectorisation.
t = 0:2:100;
h=zeros(size(t));
for k=1:numel(t);
    h(k) = rocket(t(k))
    if h(k)>=0
       disp(h(k));      
    end 
end
function h = rocket(t)
         h = (60+(2.13*(t^2))-(0.0013*(t^4))+(0.000034*(t^4.751)));
end
Without loop:
t = 0:2:100;
h = rocket(t); 
fprintf('h >= 0:%f\n',h(h>=0))
function h = rocket(t) 
         h = (60+(2.13*(t.^2))-(0.0013*(t.^4))+(0.000034*(t.^4.751)));
end
