netcdf.inq - Return information about netCDF file
Syntax
[ndims,nvars,ngatts,unlimdimid] = netcdf.inq(ncid)
Description
[ndims,nvars,ngatts,unlimdimid] = netcdf.inq(ncid) returns
the number of dimensions, variables, and global attributes in a netCDF
file. The function also returns the ID of the dimension defined with
unlimited length, if one exists.
ncid is a netCDF file identifier returned
by netcdf.create or netcdf.open.
You can call netcdf.inq in either define mode or
data mode.
This function corresponds to the nc_inq function
in the netCDF library C API. To use this function, you should be familiar
with the information about netCDF contained in the NetCDF
C Interface Guide for version 3.6.2.
Examples
This example opens the example netCDF file included with MATLAB, example.nc,
and uses the netcdf.inq function to get information
about the contents of the file.
% Open netCDF example file.
ncid = netcdf.open('example.nc','NC_NOWRITE')
% Get information about the contents of the file.
