<mofh> oh huh, the Fourier Transform of the nth Legendre Polynomial is the n'th Spherical Bessel Function (with a factor of (-i)^n out front).
<mofh> I *really* should've known that earlier, what the hell.

<egg> mofh: is NUDFT an uncommon thing? for some reason it doesn't seem to be in Mathematica itself and intsead https://library.wolfram.com/infocenter/MathSource/4746/

<egg> > All examples were solved on the computer PENTIUM 4, 1.5 GHz, 512 RAM
<egg> (or maybe there's an obvious way to do NUDFT from the tools of the language I don't know it?)
<mofh> NUDFT? I've actually never even *heard* of it, tho now that you mention it I can easily see how it'd be implemented.
<mofh> I guess I'm not sure where it'd be necessary.
<mofh> But yeah, I'm certainly not aware of a function that implements it in any common numerics package.

<egg> mofh: I don't know, observations tend not to be equispaced?
<egg> (here it's principia so the data is not equispaced for weird interpolation reasons but we could fudge it by using said interpolation)
<mofh> Yeah, fair.
<mofh> Hrm.
<UmbralRaptop> That sounds like circa 2001 hardware

<UmbralRaptop> … how did I tyop "final" as "sinal"?
<SnoopJeDi> ♫ it's the sinal countdown ♫

<SnoopJeDi> I used Impress this week and I am staggered by how bad the default UI is

<UmbralRaptop> !8 Does egg meow at the ribbon?
<galois> UmbralRaptop: yes
<SnoopJeDi> I would have loved to have the ribbon
<SnoopJeDi> but it was a throwaway slide deck to summary "graphs exist and no, this problem is not unique, someone solved it 400 years ago"
<SnoopJeDi> summarize*
