netcdf.defDim - Create netCDF dimension
Syntax
dimid = netcdf.defDim(ncid,dimname,dimlen)
Description
dimid = netcdf.defDim(ncid,dimname,dimlen) creates
a new dimension in the netCDF file specified by ncid,
wheredimname is a character string that specifies
the name of the dimension and dimlen is a numeric
value that specifies its length. To define an unlimited dimension,
specify the predefined constant 'NC_UNLIMITED' for dimlen,
using netcdf.getConstant to retrieve the value.
netcdf.defDim returns dimid,
a numeric ID corresponding to the new dimension.
This function corresponds to the nc_def_dim 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 creates a new file and defines two dimensions in
the file. One dimension is an unlimited dimension. To run this example,
you must have write permission in your current directory.
% Create a netCDF file.
ncid = netcdf.create('foo.nc','NC_NOCLOBBER')
% Define a dimension.
latdimID = netcdf.defDim(ncid,'lat',50);
% Define an unlimited dimension.
londimID = netcdf.defDim(ncid,'lon',netcdf.getConstant('NC_UNLIMITED'));
