I am making a histogram with bins of specified ranges, but I want it to be cumulative such that each bin shows the values that are in or greater than that range. I found the function cumsum which cumulatively adds the values so each column shows how many values are in or less than the specified range, but I want to do it the other way. For instance, if my values were 1:10 inclusive, cumsum gives me [1 3 6 10 15 21 28 36 45 55]. What I want is [55 54 52 49 45 40 34 27 19 10]. What function would I use for this?

Just do the cumsum backwards on your histogram output
% generating some data
% getting the histogram
% shows how many numbers are equal or less than
% Exceedance curve, shows howmany numbers are equal or greater.
% Works on MATLAB R2015a
