function [h,hdot] = roadprofile(H,L,v,t);
H=0.2;
L=1;
v=(60/3.6);
t=1;
if t <= L/v;
h =(H/2)*(1-cos((2*pi*v*t)/L))
hdot =((H*pi*v)*sin((2*pi*v*t)/L))/L
elseif t > L/v;
h = 0;
hdot = 0;
end

I cannot run your function because I have no idea what the arguments should be.
Hiowever one problem is obvious. One of the arguments is ‘t’, however you almost immediately overwrite it with:
t=1;
so the if block conditions never change.
Remove that line and you function will use the argument value you supply to it.
