This script takes in data, and then produces a logarithmically binned (natural log) histogram:
[midpoints,Freq,eFreq] =logbin(data, BinNum)
where the inputs are
data: the input data from some experiment which will be binned
BinNum: the number of bins used in the data reduction process.
The outputs are:
midpoints := the centre of each log bin
Freq := the number of counts in each bin
eFreq := This calculates the original relative Poissonian error before normalisation, then calculates the new error after normalisation.
One should note that this script is a slightly modified version of
'logbinfromlinbin.m' which can be found here:

NOTES:
This paper will be of use to some looking more deeply into the technique of using log bins in data reduction
