FIS = genfis2(XIN,XOUT,RADII) returns a Sugeno-type FIS given input data XIN
and output data XOUT. The matrices XIN and XOUT have one column per FIS
input and output, respectively.
RADII specifies the range of influence of
the cluster center for each input and output dimension, assuming the data
falls within a unit hyperbox (range [0 1]). Specifying a smaller cluster
radius will usually yield more, smaller clusters in the data, and hence more
rules. When RADII is a scalar it is applied to all input and output
dimensions. When RADII is a vector, it has one entry for each input and
output dimension.
