netcdf.inqAttName

Return name of netCDF attribute

Syntax

attname = netcdf.inqAttName(ncid,varid,attnum)

Description

attname = netcdf.inqAttName(ncid,varid,attnum) returns attname, a text string specifying the name of an attribute.

ncid is a netCDF file identifier returned by netcdf.create or netcdf.open.

varid is a numeric identifier of a variable in the file. If you want to get the name of a global attribute in the file, use netcdf.getConstant('NC_GLOBAL') in place of attnum is a zero-based numeric value specifying the attribute, with 0 indicating the first attribute, 1 the second attribute, and so on.

This function corresponds to the nc_inq_attname function in the netCDF library C API. To use this function, you should be familiar with the netCDF programming paradigm. See netcdf for more information.

Examples

This example opens the example netCDF file included with MATLAB®, example.nc.

% Open netCDF example file.
ncid = netcdf.open('example.nc','NC_NOWRITE');

% Get identifier of a variable in the file.
varid = netcdf.inqVarID(ncid,'avagadros_number')

% Get the name of the attribute associated with the variable.
attname = netcdf.inqAttName(ncid,varid,0)

attname =
