How to implement neural network in matlab using newff command

Hi, I want to implement backpropagation neural network using newff command. I have input p=[1 2;1 2] target t=[0 2] I m using newff command but it is not working properly. how can i come to know about the output and the error of network? There is another prob also. I have used nntool but it is giving wrong output. Can we have any video which can illustrate the use of nntool.

>> help newff

 newff Create a feed-forward backpropagation network.

   Obsoleted in R2010b NNET 7.0.  Last used in R2010a NNET 6.0.4.
   The recommended function is feedforwardnet.

I disagree with the feedforwardnet recommendation:

 help fitnet  % for regression and curve-fitting documentation and example
 doc fitnet   % additional info

 help patternnet % for classification and pattern-recognition documentation and example
 doc patternnet  % additional info

Both fitnet and patternnet call feedforwardnet. Feedforwardnet NEVER has to be called directly.

Use the help and doc commands for info on any function or command

Always use one of the MATLAB neural net data sets when asking a question in the NEWSGROUP or ANSWERS

 help nndatasets
 doc nndatasets
