This is a very poorly designed classifier.
My advice is to ignore it and study the classification examples in the help and doc documentation of your MATLAB version
help patternnet % or the obsolete newpr
doc patternnet
Also search the NEWSGROUP and ANSWERS for posted code. For example, search using
greg patternet
greg newpr
greg classify
greg classifier
greg classification
If you find code that interests you, post your interpretation and I will check it for you.

Not a chance. It would take several pages just to describe in detail what the "clear all" does. The code is commented. If you don't know what feed forward networks are, then research feed forward networks. If you do not understand MATLAB constructs such as net1.trainParam.lr then study MATLAB instead of asking us to write a detailed explanation.

@ASHA: Please take into account that Walter is very good in explaining. When he decides to suggest the "best ways to master matlab" thread, this is a really good answer.
