I have two lists ix and iy, an example of which is shown below. I want to match any repeating values of ix with the corresponding points of iy and then average the points in iy. For example, [4 5 6] in iy all match with 12 in ix, so I would want to average [4,5,6] = 5, and replace all the duplicate 12s in ix with just a single 12, and replace [4 5 6] with 5. Is there a simple way to do this in MATLAB?
ix = [10 11 12 12 12]; iy = [2 3 4 5 6];ixnew = [10 11 12]; iynew = [2 3 5];
