error using netcdf.putVar

 I don't see a difference when compared to the Matlab help, any idea? 

MATLAB CODE

close all

clear all

nlon=180;

nlat=90;

filenc=['slope.nc']

ncid = netcdf.create(filenc,'NC_WRITE');

%creating dimensions

dimid_lon = netcdf.defDim(ncid,'longitude',nlon);

%creating variables and attributes

varid_lon = netcdf.defVar(ncid,'longitude','double',dimid_lon);

netcdf.putAtt(ncid,varid_lon,'long_name','Longitude')

netcdf.putAtt(ncid,varid_lon,'units','degrees_east')

lont=linspace(-180,180,nlon);

netcdf.putVar(ncid,varid_lon,lont);

netcdf.close(ncid)

 this is the output:
Error using netcdflib
The NetCDF library encountered an error during execution of 'putVarDouble' function -
'Operation not allowed in define mode (NC_EINDEFINE)'.

 Error in netcdf.putVar (line 87)
netcdflib(funcstr,ncid,varid,varargin{:});

 Error in toMatlabHelp (line 15)
netcdf.putVar(ncid,varid_lon,lont);

Try adding a call to end the definition using netcdf.enddef after you define the dimensions, but before you write the variable.

Hi,

I added: netcdf.endDef(ncid2) before the defition, but I still got an error:

Error using netcdflib The number of input elements does not match the variable size.

Error in netcdf.putVar (line 84) netcdflib(funcstr,ncid,varid,varargin{:});

Error in do_air (line 131) netcdf.putVar(ncid2,tid,stmp(:,n2:-1:1,:));

Could you please offer some help?

Thanks

Did you get any solution for the same? I am also facing the same error.

Hello, I tried all the above techniques to solve the error but still it persisted. I freed some space in the drive where these nc files were generated and yes, it worked!!!

Hi, I encountered the same problem and tried your solution. It still doesn’t work. Do you know why? thx a lot!
