How does one create a NetCDF file?

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!

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!
