General code of back propagation feed forward neural network

Hi, I am looking for a general matlab code for BPFFNN I have 4 inputs and output is either 0 or 1. I need a general code which I can modify as per my requirement. Thank You

HAH!!! Trying to use one code for everything is a fool's errand. That is why MATLAB offers several generic codes for several generic categories. Use the help and doc commands to see the documentation and examples for each category:

1. FITNET - Regression and Curve-Fitting

2. PATTERNNET - Classification and Pattern-Recognition

3. TIME SERIES

 3a. TIMEDELAYNET - Time-Series with inputs consisting of either
     i) Current and delayed applied external signals
     or
     ii) Only delayed applied external signals
 3b. NARNET  - Time-series with inputs consisting of ONLY delayed 
     output feedback signals
 3c. NARXNET - Time-series with inputs consisting of delayed 
     output feedback signals AND EITHER OR BOTH  
     i.  Current applied inputs
     ii. Delayed applied inputs

4. NOTE:

   a) Timedelaynet and Narnet are SPECIAL CASES of Narxnet
   b) Causality requires that all output feedback signals must be 
      delayed from the time of the input which caused it.

Consequently, it is sufficient to be familiar with only FITNET, PATTERNNET and all variations of NARXNET.

Hope this helps.

Thank you for formally accepting my answer

In addition to the data used in the help and doc documentation, additional MATLAB data can be obtained using the following commands

 help nndatasets

 doc nndatasets

Therefore if you have questions to post, it would be very smart to use one or more of the MATLAB datasets as examples.

In addition, it would be wise to first search both the NEWSGROUP and ANSWERS before posting a question. For example, if you have a classification/pattern-recognition problem, a reasonable search might start with

 greg patternnet

Hope this helps.
