I am trying to understand how one can describe a function in matlab like the one in the picture
Would this be wrong? if not is there a better way to neatly describe a function with, in this case, a varying t value.
if t<=L/v
h=(H/2)*(1-cos((2*pi*v*t)/L));
elseif t>L/v
h=0;
end

请先登录，再回答此问题。

You can multiply the first equation by a vector that is 1 for t<=L/v and is zero when t>L/v
h=(H/2)*(1-cos(2*pi*v*t/L)).*( t<= L/v);
