What does this mean? And how do I resolve it?
>> save NARRtroughid NARRtroughid
Warning: Variable 'NARRtroughid' cannot be saved to a MAT-file whose version is older than 7.3.

type "help save" you will see some explanation regarding save Version Compatibility Options. The thing mentioned for v7.3 is that it supports for data items greater than or equal to 2GB. Is your variable a very large data?

I got it working. I guess it saves to a .mat that is 58mb but the actual size is about 3GB.
