how to combine the ouitput

I am workig om ensemble callification using anfis,I have trained and tested the code,but dont have idea on how to combine these 3 to get result,kindly tell how to proceed

clc

clear all

load fisheriris

colon_training1 = meas(:,[1,3,4,end]); 
colon_training2 = meas(:,[2,1,3,end]); 
colon_training3 = meas(:,[4,2,1,end]); 

colon_test1_f = (meas(:,[1,3,4]))'; 
colon_test2_f = (meas(:,[2,1,3]))'; 
colon_test3_f = (meas(:,[4,2,1]))'; 

% Set target matrix for test datasets 
[m n]=size(meas); test_t=[]; 

numMFs = 2; 

mfType='trimf'
epoch_n = 10; % Number of training epochs 

%  3 initial individual ANFIS models 
fis1 = genfis1(colon_training1,numMFs,mfType); 
fis2 = genfis1(colon_training2,numMFs,mfType); 
fis3 = genfis1(colon_training3,numMFs,mfType); 

% Training  the 3 individual models respectively 
result_anfis1 = anfis(colon_training1,fis1,epoch_n); 
result_anfis2 = anfis(colon_training2,fis2,epoch_n); 
result_anfis3 = anfis(colon_training3,fis3,epoch_n); 

   anfis_out1=(evalfis([colon_test1_f ],result_anfis1)) ;
   anfis_out2=(evalfis([colon_test2_f ],result_anfis2)) ;
   anfis_out3=(evalfis([colon_test3_f ],result_anfis3)) ;
