Bigger than 2GB Data Storage

Hello,
I`m a 2016B user. This version complains about my synthetic data storage and says that `For variables larger than 2GB use MAT-file version 7.3 or later.`. I cannot obtain higher version. Any idea on how to store big data?
Thanks in advance

You would probably be better splitting your data into chunks if that is possible. Saving large files to v7.3 can be very bad in terms of performance.

The message is clear already: All you have to do is to append the -v7.3 flag to your save command (see Kai's answer) or to set this as default in the preferences.

save('myFile.mat', 'Variablename', '-v7.3')
will save your variable ( > 2GB ), provided you are running on an 64-bit system

Open the documentation for the save function using doc save. In order to save your data to a MAT-file with version 7.3 or later, specify the '-v7.3' flag as the version input argument. The "Save Variables to Version 7.3 MAT-File" example on that page shows the exact syntax.
