Ali, it can only handle certain types, I didn't try to reverse engineer the entire format.

But see the comment from Raj, immediately below yours, about hlp_serialize.

See comments from 2010 for a workaround that doesn't require the Image Processing Toolbox.

Looks like it's the same idea. Thanks, I didn't know about that work.

Hi Jeremy,

Your performance benefit will depend a lot on your hard drive configuration. In my case I was writing to an SSD RAID. But on my laptop (with a single SSD) I can write in about 2.1 sec, which is still a 10x benefit. What kind of performance benefit are you getting?
