How can I put a loop here?

Hi,

Here is my code below, I want to compute and plot (del2,del) for each value of V. How can I make a loop here?

V = [0.5 1 2 3 4 6 10]; 
del = 0:10:90; 
del_r = del.*pi./180;
for i=V(:,1):V(:,end)
    x = V(:,i).*tan(del_r);
end

del_r2 = atan(x);
del2 = del_r2*180./pi;
figure, plot(del2,del) % plot for each value of V

V = [0.5 1 2 3 4 6 10].'; 
del = 0:1:90; 
del_r = del.*pi./180;
x = V.*tan(del_r);
del_r2 = atan(x);
del2 = del_r2*180./pi;
figure(1)
plot(del2,del)

figure(2)
del2 = atand(V.*tand(del));
plot(del2,del)

tot = sind(del2)./sind(del);
figure(3)
plot(tot.',del2.')

@Torsten Thanks, how to display legends? and if I compute further tot = sin(del2)./sin(del) and the plot(tot,del2); Is the correct way to compute and plot 7 curves?

Check above whether this is really what you want to plot.

You plot f(x) = atan(V.*tan(x)) against g(x) = sin(atan(V.*tan(x)))/sin(x) - quite unusual, I think. And for x=0 you get NaN for g(x).

And use sind, cosd, tand, asind, acosd, atand as trigonometric functions instead of sin, cos, tan, asin, acos, atan as you work in degrees, not radians.
