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
%/*----------------------------------------------------------------
-*
% * Main decoder routine *
%
*-----------------------------------------------------------------*
/
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).

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.
