netcdf.reDef(ncid) puts an open netCDF file into define mode so that dimensions, variables, and attributes can be added or renamed. Attributes can also be deleted in define mode. ncid is a valid NetCDF file ID, returned from a previous call to netcdf.open or netcdf.create.

This function corresponds to the nc_redef function in the netCDF library C API. To use this function, you should be familiar with the information about netCDF contained in the NetCDF C Interface Guide for version 3.6.2.

Examples

This example opens a local copy of the example netCDF file included with MATLAB, example.nc.

% Open a netCDF file.
ncid = netcdf.open('my_example.nc','NC_WRITE')

% Try to define a dimension. 
dimid = netcdf.defdim(ncid, 'lat', 50); % should fail.
??? Error using ==> netcdflib
NetCDF: Operation not allowed in data mode

Error in ==> defDim at 22
dimid = netcdflib('def_dim', ncid,dimname,dimlen);
 
% Put file in define mode.
netcdf.reDef(ncid);

% Try to define a dimension again. Should succeed.
dimid = netcdf.defDim(ncid, 'lat', 50);
