Dear ImageJ community,


You are an intelligent group of people so I would like to ask this...


Does anyone have a clever way of generating a random set of numbers that conform to a normal (Gaussian) distribution for a given mean and standard deviation using the 'random' macro function? I acknowledge that the ImageJ macro language is a slightly strange place to do this but I cannot use Excel because my data sets are so large and I would rather not learn a new scripting language (e.g. R).


For what it's worth, it is quite straightforward to do in Excel using =NORMINV(RAND(), mean, stdev). Does anyone have a clever way of replicating this function in ImageJ?


Many thanks,


Greg.
