[MITgcm-support] tutorial_offline, creating .meta and .data files for velocities

[Martin Losch]

Hi Krishnakumar,

I assume, that your matlab-fields have this shape:
u(1:nx,1:ny,1:nr,1:timelevels)
Then creating a *.data file is a simple as this (in matlab):
fid=fwrite('MY_UVEL.0000000000.data','w','b');
fwrite(fid,u,'real*4'); % or 'real*8' depending on what you want
fclose(fid);
See the matlab help for more details of these functions, if required.
For the meta file (if you really need one), I recommend to copy some other similar meta-file and edit it's contents with a text editor.

Martin
