Hi!
I have a plot where the intersection of some lines form a shape, and I'd like to fill in this area with a color to show a feasible domain!
Could someone indicate how I can do that? Thank you!
Below is the code I used to plot and the figure.
contour(D, d, fobj, 'r')
xlabel('Coil diameter D (m)'), ylabel('Wire diameter d (m)'), ...
title('Figure 1: Spring mass optimization problem (Exercise 6.1)')
hold on
contour(D, d, g1, [0.0 0.0])
contour(D, d, g2, [0.0 0.0])
contour(D, d, g3, [0.0 0.0])
contour(D, d, g4, [0.0 0.0])
contour(D, d, g5, [0.0 0.0])
