% Download the additional codes for any functions you don't have
defval('fname','Line_generic.csv')

% Read the LINES data
l=readtable(fname);

% Line codes
code=l.Var1;
% Elevation in m (e.g. above EGM96 mean sea level)
elev=l.Var5;
% Longitude and latitude in decimal degrees (e.g. on WGS84)
lat=l.Var6;
lon=l.Var7;

% Find the unique line codes
[codu,codi]=unique(code);

% That makes these the unique labels
labu=l.Var3(codi);
