What advanced mathematical functions would people want in a hypothetical 43S calculator? Assume that everything in the 34S is present. Orthogonal polynomials, real and complex functions, matrix operations and programming functions.
What else would people be interested in?
The obvious ones are Bessel functions, Bessel Zeros, Jacobi Elliptic functions, generalised Zeta functions and additional statistical distributions.
None of these are certain however, other suggestions are most welcome.

Hi Pauli, I may be listing some already in the set you mention, as I'm not really familiar with it  so pls. indulge me:
 Digamma, Polygamma
 Bessel 1st, 2nd. kind, for complex orders and arguments
 Lerch transcendental function (or this is what you called "generalized Zeta"?)
 Exponential, Sine, Cosine Integrals (and hyperbolics)
 Error function *and* its inverse (yes , I know...)
 Hankel, Struve, Kelvin, Weber, Anger functions
 Multi/Super/Hyper factorials will be nice. At least Pochhammer symbol (rising/falling factorials) should be there.
 Polynomial roots, PROOT for nth. degree. Different from FROOT (aka Solve) for degrees 2,3, and 4  using formulas instead.
 Dilogarithm, Polylogarithm perhaps
 Fourier Series / Spectral Decomposition & analysis
So do all these many polls signify that **something** is going on...??? :)
Cheers, ÁM.

I didn't know two being many ;)

This looks like the SandMath list :)
Yes, the Lerch transcendent was the Zeta generalisation I was thinking of.

As an alternative solution I suggest a "Root Cause Problem Solver for Global Warming Prognosis"?

Declined. Won't sell in the US of A. So sorry! ;)

It looks like Airbus is selling better than GW in the EU Link

Pardon me: who is GW??
BTW, seems strange that 11:22 a.m. is past 12:21 a.m.  just had to look twice at it. Oh, why can't ...

GW  Global Warming
The museum curator might be amenable to replacing the am/pm time designation. I think it's a good idea. Do you know if anyone has requested this?

Thanks for the explanation. We had some special airline tax in the EU recently but it was cut back due to USAmerican and Chinese complaints  so much about that.
About a.m. and p.m. in the museum: I bet that was no request from this side of the great pond. If you want to get rid of it, you'll have my full support  but it's up to you to start that with the museum curator.

At the risk of being told "there's a program for it already"  TVM functions (like the Finance key on the HP50g)  but with specific key assignments  eg (hshift) = N I PV FV PMT on the top row ABCDE(F?).

Well, I would be interested in a few completely different things:
1) named variables
2) true data structures:
lists, vectors and matrices (with comfortable addressing, e.g. v[i] or m[i,j]
3) better programming structures, for example:
IFTHENELSE
a generalized LOOPENDLOOP with 'IF condition EXITLOOP'
a generalized BLOCKENDBLOCK with 'IF condition EXITBLOCK'
For me such programming enhancements would be much more important than any new exotic mathematical functions (which I could then simply write myelf if I really need them).
