Return ID associated with variable name
varid = netcdf.inqVarID(ncid,varname)
varid = netcdf.inqVarID(ncid,varname) returns varid, the ID of a netCDF variable specified by the text string, varname.
ncid is a netCDF file identifier returned by netcdf.create or netcdf.open.
This function corresponds to the nc_inq_varid 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.
This example opens the example netCDF file included with MATLAB®, example.nc, and uses several inquiry functions to get the ID of the first variable.
ncid = netcdf.open('example.nc','NC_NOWRITE'); % Get information about first variable in the file. [varname, xtype, dimids, atts] = netcdf.inqVar(ncid,0); % Get variable ID of the first variable, given its name varid = netcdf.inqVarID(ncid,varname) varid = 0
