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 indicated by
attname
. Specify attname
as a character vector
or string scalar.
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.
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');
