Hi I am trying to rebin my data is discrete values.
Energy Amount
11.8652 3.5891
12.5513 6.6741
11.8652 3.5891
8.8125 1.1711

I am very thankful that Walter Roberson helped me with < * http://www.mathworks.com/matlabcentral/answers/22879-binning-for-a-histogram a very useful technique> as follows.
[uvals, a, uidx] = unique(YourData(:,1));
Sum = accumarray(uidx, YourData(:,2));
plot(uvals, Sum)
However, I am unable to bin the data in discrete bins. For example, I would like to re-bin my data from 1-2 Energy and then 2-3 Energy so and so. Bascially, I would like a histogram that shows the Energy values in the x-axis. I hope this is clear.

Sum = histc(YourData, BinBoundaries);

Sum = accumarray(binidx(:), Amount, [length(unneeded),1] )
