Hi,
I am trying to find cross-correlation without using function
xcorr
The code works for large numbers. However, for small numbers the code fail. It's round small numbers to zero. I tried to use
format longE
But it is not working. Any help will be very appreciated.
Thanks

You forgot to attach data.xlsx. Please attach it so people can try your code.

When you refer to "The code", are you referring to Mathwork's xcorr or to code that you yourself have written?

Check the code once again. You can see code of xcorr function using edit xcorr

When people are for some reason not permitted to use a particular function, then they can still often get an understanding of how the function works by using "edit" with the function name.
