Hi, I have 2 sets of data, one is 472 data points long, the other 370. They are both a function of the same variable "x", they both have the same value for "x" as the last point and the same value for "x" as the first point. I'm being asked to average the two sets of data, but obviously I can't just use "(y+y2)/2". I also can't cut the 472 data set to 370 and then average because the scale is off. What can I do? Can I have matlab average values only when they correspond to the same value of "x"? Any help would be greatly appreciated. Thanks.
