netcdf.inqVarID

Return ID associated with variable name

Syntax

varid = netcdf.inqVarID(ncid,varname)

Description

varid = netcdf.inqVarID(ncid,varname) returns varid, the ID of a netCDF variable specified by the character vector 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.

Examples

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 =
