Fuzzy Logic 'Connection' function

Hi

I have a question regarding to this website I visited.

http://www.mathworks.com/help/fuzzy/working-from-the-command-line.html

I want to learn to build a fuzzy logic controller from scratch, but I encountered a problem.

I clicked on the section of 'Building a system from scratch', and my question is what are the functions which are named 'connection' and 'weight'? What do they mean?

I understand the rest of the code but do not understand what these two functions are for. Could somebody help me please.

Thanks very much

Tommy

From addrule doc:

The m + n + 1 column contains the weight that is to be applied to the rule. The weight must be a number between zero and one and is generally left as one.

To understand how weights are used, see here and search for "weight".

The m + n + 2 column contains a 1 if the fuzzy operator for the rule's antecedent is AND. It contains a 2 if the fuzzy operator is OR. (so that's the connection).

Thank you very much for your answer, I understand now. Thanks
