Hello

I read a .csv file using the following command

IloCsvReader reader(env, "arcs.csv"); // arcs.csv is 8 by 8 table contains numbers

and I have an empty IloNumArrayArray

how I can save the values come from CsvReader in the IloNumArrayArray

Thanks

Something like this should do the trick (untested code):

IloCsvReader reader(env, "arcs.csv");
IloInt lines = reader.getNumberOfItems();
IloNumArrayArray data(env);
for (IloInt i = 0; i < lines; ++i) {
   IloNumArray lineData(env);
   IloCsvLine line = reader.getLineByNumber(i);
   IloInt fields = line.getNumberOfFields();
   for (IloInt f = 0; f < fields; ++f)
      lineData.add(line.getFloatByPosition(f));
   data.add(lineData);
}

Please see also the reference documentation of classes IloCsvReader and IloCsvLine. Looking through the available functions should already tell you how to get the table into the array.
