Below is the error I got while using divagrid on Matlab. Anyone has a solution? How do I expand the available space? My computer has 16 GB of memory and it seems to be only using 1/3 of them at most.
Many thanks!

Matlab needs contiguous blocks of free memory to store variables, so if your free memory is very fragmented you won't be able to make large variables. If you search for them on this forum, you should be able to find tips on how to maximize your array sizes.

You need to adjust a parameter and recompile. See page 181 of the user guide.

Unfortunately, I do not know how to use gcc/gfortran and MinGW to edit exe files, but thank you very much anyway!

You would edit the .h file they indicate to change those two parameters; that would require a plain text editor.
More of a nuisance is that you would need to edit the Makefile (using a text editor) to reconfigure the locations of the include files and libraries and possibly to change the names of the compilers. It is not a big deal for someone who is accustomed to using those compilation tools, but it could certainly be somewhat baffling to someone who has not used those tools before.
