What result do you want?

Try this —

figure

F = openfig('untitled.fig');

Lines = findobj(F, 'Type','line');

for k = 1:numel(Lines)

L{k}(1,:) = Lines(k).XData;

L{k}(2,:) = Lines(k).YData;

end

hold on

patch([L{1}(1,:) flip(L{2}(1,:))], [L{1}(2,:) flip(L{2}(2,:))], 'g', 'FaceAlpha',0.5)

hold off

The red dashed lines do not appear as ‘line’ objects in the .fig file. (I do not know what else they could be.) I do not see any plot or contour calls in the code that specifically plot them, either.

Commenting this line:

fill(x2,y2,'w')

to:

% fill(x2,y2,'w')

will show the red dashed-line contours betweeen the two black curves. Do the same to the other fill call to show all of them.

To show them only between the two curves, add:

patch([x2 flip(x2)], [y2 ones(size(y2))*max(ylim)], 'w')

at the end. (I added it, commented-out so it will not execute. Un-comment it if you want to use it, or simply delete it if you do not want to use it.)
