Im trying to make a graph with two plots where the one called n should only plot up to y = 0.593, but im kinda stuck on how to do that
%Variabler
A_sveip = 2.27;
luft_tett = 1.225;
%Virkningsgrad
v_0k5 = [0:0.5:30.5];
P_0k5 = [0 0 0 0 0 20 30 50 70 95 120 160 210 270 310 360 390 420 470 540 670 730 750 760 770 775 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 780 0 0 0 0 0 0 0 0 0 0 0 0];
n=[];
for i = 1:length(v_0k5)
y(i) = (2*P_0k5(i))/(luft_tett*A_sveip.*((v_0k5(i))^3));
n = y < 0.593;
end
yyaxis right
plot(v_0k5,n)
yyaxis left
hold on
plot (v_0k5,P_0k5)
