how to get the cumulative percentage of g using this coding and plot it against t?

l=input('l=')

g = zeros(1, length(0:100));% initialize g with 0's of length t

c = 1;% counter variable

for t=0:100

if t>2 && t<=80

g(c)=((3/(309*1.465))*((((12.6*(t-2))/l)*80.4)-(l/6)));

elseif t>80

g(c)=1-((80.4/309)*exp(((((-3*12.6)/(1.465*l))*(t-80)))));

else

g(c)=0;

end

c = c+1;% increment counter variable

end

format shortG

t=0:100;

plot(t,g)

gs = cumsum(g);
gs = gs / gs(end) * 100;
plot(t,gs)
