when i simulate the below code it is showing some errors.
like obsolete way of using NEWFF.
what is the new model for it ?
Can some one edit the NEWFF according to the latest version.
- load data.txt
- P = data(1:15,1);
- T = data(16:30,1);
- a = data(31:45,1);
- s = data(46:60,1);
- [py, pys] = mapminmax(P');
- [ay, ays] = mapminmax(a');
- [ty, tys] = mapminmax(T');
- [sy, sys] = mapminmax(s');
- net = newff(minmax(py),[6 1], {'logsig','logsig'}, 'triangdm')
- net.trainParam.epochs = 3000;
- net.trainParam.lr = 0.5;
- net.trainParm.mc = 0.8;
- net = train(net,py,ty);
- y = sim(net,ay);

1. That is not a clear explanation AND it seems to have little to do with your original post.
2. Why are you posting an equation that
a. is obsolete
b. has inappropriate transfer functions
c. has a misspelled training function (to which you were alerted earlier)
3. If you have 2012a, why are you trying to use the obsolete newff?
4. Now it seems that you might want the simple classifier
output = hardlim(input-5663)
4. Please clarify.
a. Single output y(t) = ( 566x.xx or 0/1?)
b. Corresponding input y( t-d:t-1)

This is a Time-Series Problem that can be solved using NARNET with a feedback delay of 15.
help NARNET
doc NARNET
Search NARNET in the NEWSGROUP and ANSWERS
Thank you for formally accepting my answer

Sorry I missed your comment. If you have any SPECIFIC questions on the code,
please post.
