Can someone can help me to find out the error
if true
% code
i=1;
j=1;
windowsize=50;
[m,n]=size(accX);
avgX=zeros(m,1);
%*******In each iteration, statistical values of a window are calculated
%and raw data(accX) index is inceremented by windowsize/2 to
%provide %50 overlapping*****%
while(i<=m)
avgX(j)=mean(accX(i:i+windowsize-1));
i=i+windowsize/2-1;
j=j+1;
end

Try this instead:
i=i+windowsize;

That depends on what ‘accX’ is, and its size. Your code worked for me with a vector I created, and produced the three values I expected when ‘accX’ was a (150x1) vector.
