Detailed Description

A block of fuzzy logic units. Treats the inputs as two concatenated vectors, whose corresponding values each form a pair to be combined with fuzzy logic to produce one output value. Example: The input {1,2,3,4,5,6} will apply fuzzy logic to the three pairs {1,4}, {2,5} and {3,6} to produce a vector of 3 output values.
