Jeffries-Matusita distance
I've calculated as follows:
matusita<-function(f1,f2,lw,up){
fmatu<-function(x) ( sqrt(f1(x)) - sqrt(f2(x)) )^2
sqrt (integrate( fmatu, lower=lw, upper=up, subdivisions=1000000)$value)
}

Cross-checking a custom function for separability indices
Hi list!
I have prepared a custom function (below) in order to calculate separability
indices (Divergence, Bhattacharyya, Jeffries-Matusita, Transformed divergene)
between two samples of (spectral land cover) classes.
I need help to cross-compare results to verify that it works as expected
(since I don't know of any other foss-tool that will give me quickly some
results).
Does anybody use another mean/tool/function (within or...

I've found a mistake: initially I used "log10" instead of "log" in the
definition of the Bhatacharryya index.
Thanks to a friend we cross-compared results of the (corrected) custom
