netcdf.inqAttID

Return ID of netCDF attribute

Syntax

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

Description

attnum = netcdf.inqAttID(ncid,varid,attname) retrieves attnum, the identifier of the attribute specified by the text string attname.

varid specifies the variable the attribute is associated with.

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

This function corresponds to the nc_inq_attid 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 netCDF example file included with MATLAB®, example.nc.

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

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

% Retrieve the identifier of the attribute associated with the variable.
attid = netcdf.inqAttID(ncid,varid,'description');
