Problem with last step of program while debugging

My code works perfect until the last line as you see at the picture

but when i click next step it give me these random numbers

I want it to stop a the detection of dogs but i does this and i dont know why

function v =  andrejbican(Signal, fs)

load('Mmfcc.mat')

% % [Signal, fs] = audioread('long_sample_1.wav');
% % if (size(Signal,2)>1)
% %     Signal = (sum(Signal,2)/2);% convert to MONO
% % end
% win = 0.31;
% step = 0.2;
%Testsamplemfcc = stFeatureExtractionmfcc(Signal, fs, win, step);
if length(Signal) < 13671
    Signal(end:13671) = 1;
end
 %spectrum model
% %  fs = 44100; 
% %  T = 1/fs;
% %  L = length(Features);
% %  f = fs*(0:L-1)/L;
% %  t = (0:L-1)*T;
% % 
win = 0.31;
%win = 0.310090703;  %% length of a single bark match with the window and step
step = 0.1;
curPos = 1;
windowLength = (win * fs); 
Stepf = round(step * fs); 
d = cell(1,1);
Length_signal = length(Signal);
numberOfFrames =  floor((Length_signal-windowLength)/Stepf) + 1;

 
  % = Featuresaudio(1:windowLength);
% % Featuresaudio 
% [Features] = getDFT(Featuresaudio, 44100);
 
Ham = window(@hamming, windowLength);
for i = 1:numberOfFrames
    frame  = (Signal(curPos:curPos+windowLength-1));
    %frame  = frame .* Ham;
    Curframe{i} =  stFeatureExtractionmfcc(frame, fs, 0.08, 0.03);
    %Curframe{i} = mean(Curframe{i},2);
    Curframe{i} = Curframe{i};   % in case of transposing
    d{i}= ((Curframe{i}-mfccFeatures{1}).^2);
    d{i} = sum(d{i});
    d{i} = sum(d{i},2);

    curPos = curPos + Stepf;
   
end

d = cell2mat(d);

idx = zeros(1,1);
if all(d(:) > 230)
        fprintf('Dog wasnt found in any frame')
else 
   idx  = find(d(:) < 230);
         %fprintf('Dog detected in frame number %d\n',idx(:))
         for i = 1:length(idx);
     idx(i) = idx(i) *0.1;
 end 
 
 idx = round(idx,2);

  fprintf('Dog detected at second %0.2f\n',idx(:))  


end

these are my 2 functions Iam calling with the one below

function [Signal, fs] = callingmfs(sample)

[Signal, fs] = audioread(sample);

if (size(Signal,2)>1)
     Signal = (sum(Signal,2)/2); % convert to MONO
end

andrejbican(Signal, fs);

As you do not show how callingmfs is being invoked, my suspicion would be that you are seeing the output from callingmfs() as I speculate that you did not put semi-colon on the end of the call to it.

[Kamil Kacer]

Exactly i was calling it without semicolumn.

callingmfs('test1nodog.wav');
this is correct
