Everytime I try to run a program that has a plot, I get an error like this
Error using gca
Can't reload 'C:\Program Files\MATLAB\R2015b\bin\win32\handle_graphics.dll'
Error in hold (line 34)
ax = gca;
Error in PredictorSmithP4 (line 20)
hold on;
This happens only with my laptop. But this is the first time it happens, so I don't think it's a memory problem since it has worked properly before.
Just in case, it has 2 GB of RAM which should be enough for MATLAB 2015b.

Well, apparently it had something to do with Windows' registry. As dumb as it sounds, running CCleaner's registry cleaner fixed the problem. Probably a shared DLL issue like you said. Thank you.

When I was searching, I did see one site claiming the problem had to do with bad registry entries, but since the site was pushing a particular commercial registry cleaner (one that I had not heard of either), I considered the claim to be unreliable.
