hi all, i want to ask something about getting coordinates from the value of something using matlab, soo i have this code :
R = HarrisMeasure(x,y);
R = abs(R);
sortedR = sort(R,'descend');
best = sortedR(1:50,:);
x and y is the inputed coordinates, so how can i get the coordinates after i sorted it? how can i get coordinates of 'best'? thank you

Please notice, that we do not know, what your function HarrisMeasure does. So how could we guess, how x,y are correlated to R?

Look at the second return argument from sort(). I think you can use that.

Impossible to know, because I don't know what HarrisMeasure does. You need a function that does the inverse of HarrisMeasure(), like
[x, y] = InverseHarrisMeasure(R);
but I imagine there are lots of x,y that could have a particular R value.
