[MITgcm-support] Matlab for post-processing!

[Van Thinh Nguyen]

Hi Matt & Dimitris,

I knew how to reduce the memory use by reading only one rec at each 
time step or each tile by:

(ex: T=rdmds('T.0000000400'; rdmds('T.0000000400.001'); 
rdmds('T.0000000400.001.001')

Unfortunately, since I used option usesinglecpuio=true, I got the output 
at each time step only one couple *.data & *.meta, so they are quite 
large.
I am not sure what Dimistris mentioned "read on each level as a 2D", my 
simulation is 3D.

Thanks

Vth
