From: Jean-Philip Dumont on 27 Jul 2010 15:06 Hi, I Have a main structure called "Results". In that structure, I have other structures that each contain different series. The series in each structure have the same name. For example, let say I have an exchange rate time serie from t=1 to T that is called S1. This serie finds itself in Results.Trend.S1. I also have the Dates, Tbill and Vol corresponding to those data (corresponding to the same dates) that find themselves in : Results.Tbill.S1 Results.Vol.S1 Results.Dates.S1 Let say I would like to delete S1 in all the structures, is there a way of doing this instead of writing four lines? Results.Trend = rmfield(Results.Trend, 'S1') Results.TBill = rmfield(Results.TBill, 'S1') Results.Vol = rmfield(Results.Vol, 'S1') Results.Dates = rmfield(Results.Dates, 'S1') Thank you very much! JP
