Apply TodayYou have a phenomenon that produces strictly positive or negative results.

delta = [1 -3 4 2 -1 6 -2 -7];

Marching through this list from beginning to end, mark a value with -1 if it is the greatest magnitude negative yet seen (strictly greater, not equal). Mark it with a one if it has the greatest magnitude in the positive direction (strictly greater, not equal). Just use a 0 if neither of these conditions have been met.

The result for the above example would be:

result = [1 -1 1 0 0 1 0 -1]

Very nice the construct to avoid (for example) meshgrid!!
also the use of 'minus' to avois the use of double(...)-double(...)
Very interesting!
