What do I need to change to output variables larger than 2 GB in MATLAB?

When I export workspaces with variables less than 2 GB no problem, but even when I try to output structures of more than 2 GB with no variable larger than 500 MB the export fails with no problem even reported. Is this fixed in new version, I'm running 2012B or operating system, I'm running Windows 7?

I might have misinterpreted your question. The functions save and load use mat-files to store and recover workspace data. I believe you refer to that with the words "export workspaces" and "output variables ".
Over time new mat-file formats have been added to Matlab. See MAT-File Versions. No new mat-file format has been added after R2012b.
"saving from the GUI". I assume you refer to the Matlab "desktop", not a GUI that you made. With R2013a (and R2013b?) there is no obvious way to occasionally save to '-v7.3'. Default is '-v7.0'. The only way I find is setting '-v7.3' in Preferences, General, MAT-files. However, you might not want to do that because the files become larger and slower(?). Command-line might be a better alternative to use occasionally.
