Dear Sir,
This part of my code...I don't know why I have this error "??? Index exceeds matrix dimensions"...
T =[];
for j = 41:41:492
S1Secondcell1 = x1Firstrow16 (j+1: j+j, :);
X1= S1Secondcell1 (:,1);
Y1 = S1Secondcell1(:,2);
p1 = polyfit(X1,Y1,20)
T = [T; p1];
end

You don't supply enough information to make it possible for us to find the cause of the error.
Here are some links on debugging in Matlab
Hint: what does
size( x1Firstrow16 )
return?

I rather think your trouble is caused by the way you indexed the array 'x1Firstrow16'. Its rows are successively indexed as:
41:82
83:164
123:246
165:328
.......
493:984
These are overlapping each other more and more as j increases. Somehow I doubt if that is what you meant to do, and I doubt that the array has 984 rows. You can check that easily with the 'size' command.
