FIS AND GUIDE - SOS

Hi, Ca I am working on a medical expert system which uses fuzzy logic to diagnose an ailment whose clinical features (FIS input variables) are A, B, C and D respectively while E is the FIS output variable. The Fuzzy Inference Systems (FIS) produced an output (value) for each combination of the above clinical features (FIS input variables)using Fuzzy Logic 'AND'. For instance: When A = 15.00, B = 1.50, C = 1.80 and D 2.00, E (Output) = 37.50 , When A = 22.50, B = 1.64, C = 2.30 and D = 2.38, E (Output) = 50.00 and When A = 21.70, B = 2.13, C = 2.40 and D = 2.56, E (Output) = 84.00 But I am unable to get an output for each combination of them in GUIDE (Graphical User Interface Development Environment). In a nutshell, your help is needed on how to send FIS output (value) to a particular statictext or edittext in GUIDE and how to link FIS to GUIDE using MATLAB software such that one will not need to go to the command line and type ‘evalfis’ command on each occasion. Thanks.
