The code below uses matplotlibd but is not necessary. The timing code is
lower.
Ideally I'd like to have quadratic interpolation and all that but if the
code is going to be slower and less accurate then what is the point?
Surely I'm doing something wrong?
I wasn't able to test this with LDC because it's giving me linker errors
for some reason.
I'm also curious as to what D is using internally in the first place.
It should be the libc's.
With regards to your code, it looks like your computation is wrong.
I gave it a go (although refactored) and it just wouldn't output the
right set of values. So performance isn't all that important right now.
