Hi all

I have input p 5x101 cell and target t 1x101 cell. I want to use timedelaynet function to predict this time series. I write this script:

net = timedelaynet(1:8,10);

[Ps,Pi,Ai,Ts] = preparets(net,p,t);

The following error occurred:

Error using preparets (line 161) The number of input signals does not match network's non-feedback inputs.

Error in TimeSeriesPreduction (line 9)

[Ps,Pi,Ai,Ts] = preparets(net,p,t);

Hi every one,

                 Can any one  please guide me how to divide and prepare input and target cell from the raw data... can u please tell me what is the procedure for time series prediction... starting from beginning...??

please help me out...

The created net does not know it is going to have a 5-dimensional input.

view(net)

Therefore, tell it by using CONFIGURE (help/doc) .

view(net) % Checking

Hope this helps.

Thank you for formally accepting my answer

And what about if I have multiple time sequences on which i want to train my network?
