project. The exception is the Output Takagi-Sugeno Variable. To
change the default or to modify the existing terms setting you need to
open the Term Editor dialog (see Input Term Editor for Input

Variable). Open the editor by clicking Term Editor, or double-clicking
a variable in the project window or tree view.
The Term Editor consists of two main parts, the membership function
editor and the table of term DOFs (DOF - degree of fulfillment). The
membership function editor does not exist for the Output
Takagi-Sugeno Variable and for the Intermediate Linguistic Variable.
