im trying to use the short-term forecast for electricity load using neural networks.i've found an example here in mathworks.com for the new england iso and before to continue with my datas i want to test it but i have a problem. If using the MATLAB Central File Exchange script, load the MAT-files from the Data folder and skip to line 74. _data = fetchDBLoadData('2004-01-01', '2008-12-31'); addpath ..\Util...i dont know how to proceed.i have to open fetchDBLoadData script and then to go to line 74 or i shouldn't open this script?!please help me

Geoff thanks for answering.this is the link http://www.mathworks.com/matlabcentral/fileexchange/28684-electricity-load-and-price-forecasting-webinar-case-study/content/Electricity%20Load%20&%20Price%20Forecasting/Load/html/LoadScriptNN.html..i have downloaded all this material and i have found the data from 2004 to 2008..my problem is here:
If using the MATLAB Central File Exchange script, load the MAT-files from the Data folder and skip to line 74.
data = fetchDBLoadData('2004-01-01', '2008-12-31');
addpath ..\Util
in which script i have to skip to line 74?

The paragraph above that says the function retrieves data from an Access database, and implies that if you have downloaded from File Exchange, you should instead load the MAT files. So you should skip to line 74 in whatever file is making those calls to fetchDBLoadData(), NOT in the fetchDBLoadData script.

i load the MAT files from Data folder and than nothing happens and i dont know in which file i should skip to line 74...the example above is for matlab R2010 but im using matlab R2011.is this a mistake?..thanks

I hven't downloaded or tried this, hence not really answering your question.. But do you have the variable called holidays? If so, continue from the section on that page that says "generate predictors". Otherwise do the "import holidays" part first.

I am writing a program on matlab for the power generation of wind power plants foercasting using neural networks. I'm having trouble with this issue. I need the code file of electricity load forecasting using neural network or a similar program file for reference. If you have any help please me. Thanks very much
