Well, you are using the command wrong.

netcdf(file_name) is not a command.

Note that MATLAB version 2010a was only supporting the kinda one-to-one mapping of (C/FORTRAN) NetCDF api. Recent versions of matlab have other commands that are much easier to read and write a netcdf file. for example ncdisp is not supported in MATLAB 2010a. Neither is ncread.

In that older API you can read a file like this:

% Open the NetCDF file
ncid = netcdf.open('example.nc','NC_NOWRITE');
% returning information from the files:
[ndims,nvars,ngatts,unlimdimid] = netcdf.inq(ncid)
% getting information about a variable
%varid is an integer from 1 to nvars (nvars is the output of previous command.
[varname,xtype,dimids,natts] = netcdf.inqVar(ncid,varid)
% Reading the entire variable
data = netcdf.getVar(ncid,varid)
