Scientific computing in D

[Márcio Martins via Digitalmars-d]

I have been running some MCMC simulations in Python and it's hard 
to cope with how unbelievably slow it is.
Takes me almost a minute to run a few hundred thousand samples on 
my laptop whereas I can run the same simulation with a million 
samples in under 100ms, on my phone with JavaScript on a browser.

Then, you spend a minute waiting for the simulation to finish, to 
find out you had an error in your report code that would have 
been easily caught with static typing. So annoying...

Is anyone doing similar stuff with D? Unfortunately, I couldn't 
find any plotting libraries nor MATLAB-like numerical/stats libs 
in dub.

This seems like another area where D could easily pick up 
momentum with RDMD and perhaps an integration with Jupyter which 
is becoming very very popular.
