MATLAB: Is there a way I can merge figure two and figure three in the same figure? Trying to make a 3D movie and having the two figures in one would reduce developing time and editing.

Best Answer

Something like,
hfig = figure('Position',[100 100 401+401 601],'color',[0 0 0]);
hfig1 = axes('ytick', [], 'xtick', [], 'yticklabel', [], 'xticklabel', [], 'color', [0 0 0], 'Units', 'pixel', 'position',[0 0 401 601], 'Xlim', [-100 100], 'ylim', [-150 150]);
Yes, I know that hfig1 suggests a figure but you are storing an axes in it. That saves you from changing the line
T = getframe(hfig1);
Then later
hfig2 = axes('ytick', [], 'xtick', [], 'yticklabel', [], 'xticklabel', [], 'color', [0 0 0], 'Units', 'pixel', 'position', [402 0 401 601], 'Xlim', [-100 100], 'ylim', [-150 150]);
Again with the strange naming to avoid changing the line
T = getframe(hfig2);
I would use a name that reflected an axes, but that's me...
If you are creating a movie then you should set these up first and then update their contents within the loop. Your current code creates one new figure for every iteration, because of the
hdig = figure;
near the bottom of it.
