How to write a fusion code

Hello, I'm getting this error message

Error in score_total (line 25) output = My_predict(mdl,mdl2,tst_dat);

Here's how I used the code:

clear all
load my_ftrs_LBP
features_LBP =[];
trn_per_paper = 1;
for i = 1:50
    img = fetch7_P{i};
    features = extractLBPFeatures(img);
    features_LBP = [ features_LBP; features ];
end
save my_ftrs_LBP fetch7_P features_LBP all_labels_LBP
[trn_dat, trn_lbl, tst_dat, tst_lbl ] = splitTrainTest(features_LBP,all_labels_LBP,trn_per_paper);
mdl=fitcknn(trn_dat, trn_lbl);
results = predict(mdl, tst_dat);
mdl2=fitctree(trn_dat, trn_lbl);
results2 = predict(mdl2, tst_dat);
output = My_predict(mdl,mdl2,tst_dat);
[lbl,scr] = predict(mdl,tst_dat);
[lbl2,scr2] = predict(mdl2,tst_dat);
tot_scr = scr1+scr2;
[val posn] = max(tot_scr,[],2);
output = posn

Please check if my reconstruction of your code is the same as your code.

Also, you should share the complete error message (all the red text).

Your code causes a lot of confusion and questions. Why are you clearing everything? Why aren't you loading to a struct? Why aren't there any comments explaining what is hapening?

Hello the error says I need to declare my_predict() function before calling it. So I guess my question is how do I declare it?

This doc page should help. Note that Matlab is case-sensitive, so if you have defined my_predict(), but not My_predict() this error will still occur.
