I have the figure in attached and I need to extract values.
I run this code:
F = openfig('phi_1.fig');
ax = gca;
lines = findobj(ax, 'Type','Line');
for k = 1:numel(lines)
x{1,:} = lines(k).XData;
y{k,:} = lines(k).YData;
end
the problem is that I don't get a vector, but a matrix with other matrix inside and I don't know how to extract the values.
For the x I don't have problems, I type:
time=cell2mat(x);
but for the y I don't know

Change the code slightly to:
F = openfig('phi_1.fig');
ax = gca;
lines = findobj(ax, 'Type','Line');
for k = 1:numel(lines)
x{k} = lines(k).XData; % Force Row Vector
y{k} = lines(k).YData; % Force Row Vector
end
xv = cell2mat(x); % Extract From Cell Array
yv = cell2mat(y); % Extract From Cell Array
[xvs,idx] = sort(xv); % Sort Ascending
yvs = yv(idx); % Sort According To ‘xvs’
figure
plot(xvs, yvs)
grid
That should do what you want.
