Dear Greg,
the RandomJ plugin from Eric Meijering looks to me what you are asking for.
https://imagescience.org/meijering/software/randomj/The only limitation it works on images. However it is macro recordable and the source code can be found on GitHub.
Best
Arne

Subject: Gaussian Random Number Generation
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.
