You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: nc_read.m
    path of file: ./repos/tracacode/1911-COAWST/script/mfiles/rutgers/netcdf
    
    the code of the file until where you have to start completion: function f = nc_read(ncfile, Vname, Tindex, ReplaceValue, PreserveType)

%
% NC_READ:  Read requested NetCDF variable
%
% f = nc_read(ncfile, Vname, Tindex, ReplaceValue, PreserveType)
%
% This function reads in a generic variable from a NetCDF file. If only
% the water points are available, this function fill the land areas with
% zero and returns full fields.
%
% On Input:
%
%    ncfile        NetCDF file name or URL name (string)
%
%    Vname         NetCDF variable name to read (string)
%
%    Tindex        Optional, time record index to read (integer):
%                    If Tindex is provided, only the requested time record
%                    is read when the va

% Open NetCDF file.

ncid  = netcdf.open(ncfile, 'nc_nowrite');
varid = netcdf.inqVarID(ncid, Vname);

% Read in data: scalar or multi-dimensional array.

if (nvdims == 0)
  f = netcdf.getVar(ncid, varid);
else
  f = netcdf.getVar(ncid, varid, start, count);
end

% Close NetCDF file.

netcdf.close(ncid);

% Search for fill value or missing values.

    ind = find(f == spval);
    f(ind) = spval;
  else
    ind = find(abs(f-spval) < 4*eps(double(spval)));
  end
