Hi,
I would like to cross-correlate a vector (x) with each row of a matrix (26X5501). Is it possible to do that? which function can I use.
I tried xcorr but it didn't work for me.
Thanks

x = randn(40, 5); % better to make it column dominant order for speed
y = circshift(x(:,1), 5);
for i=1:size(x, 2)
[c{i},lags] = xcorr(x(:, i),y);
end
plot(lags, c{1})
