Is there a better way or more efficient?
n = 3500;
t_s = 0;
t_f = 3500;
t = linspace(t_s,t_f,n);
a = zeros(1,n);
for i = 1:1800
a(i) = 50/3.6;
for n = 1800:3000
a(i) = 90/3.6;
for n = 3000:3500
a(i) = 0;
end
end
end

Replace the loops by
a(1:1800)=50;
a(1801:3000)=90;
a(3001:3500)=0;
to match the figure
