problem with feed-forward backpropogation

I want to design a feed-forward back propagation neural network in Matlab. I have data(prices) and all of them (1500days) are in an Excell file. I want the data to be fed into network one by one. I mean days 1,2 and three be fed into network and day 4 is my target, then day 2,3 and 4 will be fed into network and day 5 will be my target and so on. how could I do this? Is there any GUI for doing this? I don't have separated file for my target.

[Greg Heath]

size(data ) = [ 1 1500 ]

 input  = data(1:end-3);
 target = data(4 : end);

Hope this helps

Thank you for formally accepting my answer
