The argument to openfig should be a single .fig file, so supply the appropriate information for ‘filename’ here.
Other than that, this should work —
fig=openfig('filename.fig');
Ax = gca;
Lines = findobj(gca, 'Type','Line');
for k=1:numel(Lines)
xv{k} = Lines{k}.XData;
yv{k} = Lines{k}.YData;
end
Assigning them to cell array elements is necessary because they may not all be differnt sizes or orientatioons.
Make appropriate changes to work with your files.
