Hi
is there a way of saving large figures (>2GB) in matlab?
savefig(fig1, strcat(self.imageAddress, '.fig'), 'compact');
results in error: 'Error closing file ... The file may be corrupt.'
I've also tried:
save(strcat(self.imageAddress, '.fig'), 'fig1', '-v7.3')
and the saving works but then
fig = openfig(strcat(self.imageAddress, '.fig'));
gives me an error: 'Invalid Figure file format.'
Best,
Dawid

Hi Dawid,
Kindly follow the below procedure -
  1. Go to Preferences
  2. Go to General
  3. Click MAT-Files and select "MATLAB Version 7.3 or later".
  4. Then save the figure using savefig().
You can also use the compact option as the last parameter (doc link) since this option results in smaller .fig files.
