Step 6 error For variables larger than 2GB

Hi everyone
I have a problem when doing step 6 (stamps (6,6), I am using 24 interferegrams,

The problem indicates that the variables were not saved because they were larger than 2 GB.

Warning: Variable ‘dph_space’ was not saved. For variables larger than 2GB use MAT-file version 7.3 or later.

Warning: Variable ‘dph_space_uw’ was not saved. For variables larger than 2GB use MAT-file version 7.3 or later.

Have you ever generated this problem? How could I solve it?

If I redevelop the study area, could it work?

This is a Matlab configuration issue. Try setting Matlab preferences to use MAT-file version 7.3 or greater.
