Hi, I have two matrices (same data from two reading) at some point they match each other, As you can see A(39,2) is 800 and A(400,2) = 798, A(18,1) is 800 followed by A(19,1) = 798. These data are out of sync, I'm trying to match them. Any suggestion?

Are you trying to align the two signals so [800 798] in column 1 matches [800 798] in columns 2? In that case you can try alignsignals

If you release does not have this function, then yo can consider using xcorr

Thanks, for some reason, alignsignals doesn't work properly. I attached my matrix as a text file.
