netcdf.defVar - Create netCDF variable
Syntax
varid = netcdf.defVar(ncid,varname,xtype,dimids)
Description
varid = netcdf.defVar(ncid,varname,xtype,dimids) creates
a new variable in the dataset identified by ncid.
varname is a character string that specifies
the name of the variable. xtype can be either a
character string specifying the data type of the variable, such as 'double',
or it can be the numeric equivalent returned by the netcdf.getConstant function. dimids specifies
a list of dimension IDs.
netcdf.defVar returns varid,
a numeric identifier for the new variable.
This function corresponds to the nc_def_var function
in the netCDF library C API. Because MATLAB uses FORTRAN-style ordering,
the fastest-varying dimension comes first and the slowest comes last.
Any unlimited dimension is therefore last in the list of dimension
IDs. This ordering is the reverse of that found in the 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 netCDF file, defines a dimension
in the file, and then defines a variable on that dimension. (In netCDF
files, you must create a dimension before you can create a variable.)
To run this example, you must have write permission in your current
directory.
% Create netCDF file.
ncid = netcdf.create('foo.nc','NC_NOCLOBBER');
%
% Define a dimension in the new file.
dimid = netcdf.defDim(ncid,'x',50);
% Define a variable in the new file.
varid = netcdf.defVar(ncid,'myvar','double',dimid)
