I understand that you want to update the title of a figure after saving it.
You can follow these steps:
myfig = openfig("name_of_my_fig.fig");
% Access the axes of the figure using the 'gca' function:
ax = gca;
% Modify the title of the plot using the 'title' function:
title(ax, 'New Title');
% Optionally, you can update the figure to reflect the changes:
drawnow;
% If you want to save the modified figure with the new title, you can use the savefig function again:
savefig('myfigure_modified.fig');
