I have the same problem like Ali in May 2011. Solution?
The fun (genPredictors.m) it showed the errors as shown below:
??? Input argument "data" is undefined.
Error in ==> genPredictors at 27
dates = datenum(data.Date, 'yyyy-mm-dd HH:MM:SS') + (data.Hour-1)/24;
Could you please kindly solve the problem?
In order to forecast the electricity price of the day ahead Dutch market I am using neural networks and real data from 2007-2011.
I constructed the X matrix as you said in the webinar for load forecasting and proved with different combinations. The one with gives me the lower MAPE value consists of 8 inputs (Hour dayOfWeek isWorkingDay prevWeekSameHourPrice prevDaySameHourPrice prev24HrAvePrice prevDayNGPrice prevWeekAveNGPrice), but I can't reduce this value more than 11%.
I need to achieve better accuracy but I don't know whar should I change. Could you send me an example of who to forecast the day ahead electricity price? My email is email@example.com
Thank you in advance.

I tried to run the loadscriptNN but everytime it went to fatal error. I needed to close the matlab.
I also tried to follow your webinar but there is an error in the fetchDBLoaddata. It said "Undefined function or method 'fetchDBLoadData' for input arguments of type 'char'". Please clarify this. Thank you.
I hope you are in good health.
