Thread Subject: time merger

Hi
I'm trying to merge two sources of data. I have values for
pH vs. time and also potential vs. time. I want to merge
these two so I can get pH vs. potential. The times are not
exactly the same so I tried to write an m-file that would
match up the times as close as possible and give me an array
of pH and potential. It's not working so far. Any help is
greatly appreciated.


Thanks :)

Probably you want to interpolate one of the signals at the
time data of the other one. Check out
doc interp1
so you'll get, say, the pH vs. the interpolated potential.
