A problem occur in code debugging

Hello..I have some same types of codes.But out of them some codes can be successfully debugged,while some codes show an error message and can't be successfully debugged.

%function main

clear all;

clc;

fid=fopen('coding670_r.bit');

speechin= fread(fid,'int16');

fclose(fid);

for i=1:length(speechin)

      if speechin(i)==127

          speechin(i)=0;

      else if speechin(i)==129

              speechin(i)=1;

          end

      end

end

tic

bitstream=enframe(speechin,82);

bitstream=(bitstream(:,3:end));

QuanJuValuedecode();

s=zeros(1,80);

speechout=[];

%tic

for i=1:size(bitstream,1)

      a=dec2bin(bitstream(i,:));

      a=a';     

      %C1 C2 P0 P1 P2 S1 S2

      [L0,L1,L2,L3,P1,P0,S1,C1,GA1,GB1,P2,S2,C2,GA2,GB2]=destream(a);

      [s,Az_dec,T2]=G729decode(L0,L1,L2,L3,P1,P0,S1,C1,GA1,GB1,P2,S2,C2,GA2,GB2);

      %round(Az_dec*2^12)'

      %T2

      syn_pst=Post_Filter(s, Az_dec, T2);        %/* Post-filter */

      synth=Post_Process(syn_pst);

      speechout=[speechout,synth];

end

toc

speechout=speechout/2^15;

wavwrite(speechout,'syn_speech670_r');

[ABSE,MSE,SNR,duration]=objectiveanalysis(speechin,speechout)

*Error:??? Attempted to access u1(201); index out of bounds because numel(u1)=200.*

It doesn't appear you provided the relevant code. The error message refers to a variable u1, but I do not see a variable u1 in your code. You need to narrow down where the problem is. What line of code is causing the problem (the error message may tell you).

I have check all related codes to this code,but I did not find anywhere u1.

and also error message doesn't show the line of code having problem.

That's why I am confuse that what type of error is this?

[Daniel Shub]

Then you need to evaluate each line in the code you posted one-by-one until you find the problem. Basically, cut and paste everything up to, but not including, the "main decoder routine." Does that cause the error? Once you find the error you should be able to cut out lots of the code and post a minimum example that shows the problem.
