[Scilab-users] Avoiding a loop

[Frieder Nikolaisen]

There was a piece of code missing: 

P = [
1, 0; 
2, 50; 
5,
110;
10, 80;
11, 200
15, 0];

batt = 1000;
gen = 0;

n = 1
for n=1:5


if P(n,2) > 100 then
 if batt > 800 then batt = batt - P(n,2) *
(P(n+1,1) - P(n,1))
 else
 gen = gen + P(n,2) * (P(n+1,1) - P(n,1))

end

 else
 batt = batt - P(n,2) * (P(n+1,1) - P(n,1))
 end
disp('n ' +
string(n))
disp('batt ' + string(batt))
disp('gen ' +
string(gen))
end
