Hi all,
I'd like to export data as a netcdf file. Below is an example code:
dc=5000;dl=5000;
data=rand(dc,dl);
nccreate('test.nc','sample','Dimensions',{'r',dc,'c',dl},'DeflateLevel',6);
ncwrite('test.nc','sample',data);
Here, the file size of 'test.nc' is about 200 MB - this is too big. Could anyone tell me a way to make the file smaller?
Thanks

Convert the variables to single and then write to nc file. Read about Single.
