MATLAB: How to fill the area between these two curves? I tried using fill function along with the flipud and fliplr function but the problem is both the curves have different x and y value.s.

Answer 1

Try this:

figure
plot(x1, y1,    x2, y2)
hold on
patch([x1; flipud(x2)], [y1; flipud(y2)], 'g')
hold off

They are column vectors, so you need to concatenate ‘x1’ with the flipped version of ‘x2’, and the same for ‘y1’ and ‘y2’ (where (x1,y1) are the first curve, and (x2,y2) the second curve).

EDIT — Added plot image.
