Function File: res = fl_union(A, B)

Function File: res = fl_union(A, B, S)

Returns the Fuzzy Logic union. A and B must be both row vectors or both column vectors.

The argument S allows to specify a custom S-Norm function. So it can be:

• 'max': use the maximum S-Norm (same as fl_union(A, B));
• 'sum': use the probabilistic sum S-Norm;
• function_handle: a user-defined function as S-Norm.

Note that only maximum and probabilistic sum S-Norm will be calculated rapidly and in multithread mode. Using a user-defined function as S-Norm will result in a long time calculation.
