Question
Two fuzzy inference system(FIS) has different input features where both FIS have same output classes. I need to combine both FIS and get single output. Which block i need to use in the library browser (Simulink) to combine them to get single output.   As i need to form more rule so i done two sets of fuzzy inference system to reduce the rules.     Please help me how to combine them in simulink to get single output.

and then the final output is
