I have a varaibale of size >2GB. I wanted to save it. So matlab shown me an error when I used ordinary save command [save info.mat info;] like below.

For variables larger than 2GB use MAT-file version 7.3 or later.

So i switched to

save ('info.mat','info', '-v7.3');

Now when I use this, It is taking aound 30-40 minutes to save that variable!!

Is there any way out I can quicken this process in several seconds..??

Please help!

Anyway I have saved the variable after waiting for 30 minutes.

Can you please help me for my next question on loading the saved variables...

It has only one variable saved inside with 52x1 cells. Is there any way I can access few cells amongst entire variable?
