Okay, so in the code I gave, temp should give you
a sorted view and ranking should give the indexes of
elements in the sorted array.

Given
[4](0.405121, 0.943918, 0.887914, 0.338921)
the code outputs
1 3 2 0

You can just match them up elementwise to
get the correct exponents.  If this doesn't
work please post the complete code and output
that demonstrates the problem.
