I need to find maxima in lists of numerical (measured) data. My basic idea is to apply Differences[] to the data and find pairs which differ in Sign[]. My working solution is:
AllMaxima[lst_] :=
Flatten[Position[
Partition[Differences[lst], 2, 1], {x_, y_} /;
Sign[x] > Sign[y]]];
which behaves as i want. Since it was hard to work this out, i ask myself whether i haved overlooked the simple solution. So does anybody know the really cool way to achieve this?
Greets!
