Hi there!
I am desperately trying to create a NetCDF file that would include latitude, longitude and depth, to use as a bathymetry file in Ocean Data View. Here is the script that I came up with:
my_data = [lat lon depth]';
ncid = netcdf.create('sagbathy','NOCLOBBER');
dimid = netcdf.defDim(ncid,'my_dim',size(my_data));
varid = netcdf.defVar(ncid,'my_var','NC_BYTE',dimid);
netcdf.endDef(ncid);
netcdf.putVar(ncid,varid,my_data);
netcdf.close(ncid);
For some reason, the output ends up being a single number.
Could someone help me write the appropriate script?
Thank you so much!
Louise

Have you tried ncwrite? The process for writing netcdf files is described here.

The script that I 'wrote' uses this page but I think I must be getting something wrong somewhere. I'm new to Matlab so I don't understand every line just yet!

You're right, the procedure for writing NetCDFs is rather convoluted and unintuitive, so it's hard to diagnose the problem. I wish I could offer more help!
