I want to make an increment for loop to do an autocorrelation in a signal processing, but i've got an error. Can anyone help me? Thanks, and this is my code :

Fs = 1600        ;
t  = (0:1/Fs:1-1/Fs)  ;
L  = length (t)  ;
f1 = 100         ;
A = 0.8       ;
y = A*sin(2*pi*f1*t);
[q,w] =size(x);
row = [];
for i = 1:w;
    row(i) = y(1,(i+1):1:2)
    [cr1(i),lgs1(i)] = xcorr(row(i),'coeff');
    if cr1(i) < 0.8
        row(i) = medfilt2 (row(i),20)
    end
end
disp(row(i))
figure();
plot (lgs/Fs,cr);
