Missing functions on the HP Prime!!!??? :-( - Printable Version +- HP Forums (https://archived.hpcalc.org/museumforum) +-- Forum: HP Museum Forums (https://archived.hpcalc.org/museumforum/forum-1.html) +--- Forum: Old HP Forum Archives (https://archived.hpcalc.org/museumforum/forum-2.html) +--- Thread: Missing functions on the HP Prime!!!??? :-( (/thread-248589.html) Missing functions on the HP Prime!!!??? :-( - Namir - 08-21-2013 After exploring the wealth of math functions and polynomials on the HP Prime emulator, I noticed that the following functions were missing: 1) Bessel functions 2) Bernoulli numbers 3) Bernoulli polynomials The history of HP calculator has supported calculating some of the Bessel functions, of integer orders, in the Math Pacs of various vintage calculators (in fact I was playing with the HP-67 Math Pac today and calculating Bessel function values). The Bernoulli numbers and polynomials have never been implemented in any HP calculator math pac. I am asking about these functions since the Prime now supports, for the first time, various orthogonal polynomials (Laguerre, Legendre, Hermite, and Chebyshev). So why not add Bessel and Bernoulli functions as new functions???

IMHO TW Re: Missing functions on the HP Prime!!!??? :-( - Gerson W. Barbosa - 08-21-2013 Zeta for complex arguments is one of them. Gerson. Re: Missing functions on the HP Prime!!!??? :-( - Eddie W. Shore - 08-21-2013 That is the awesome part of calcualtors being programmable; it can be used to fill any missing holes and customize the calcualtor. Re: Missing functions on the HP Prime!!!??? :-( - Mic - 08-22-2013 exactly, just program it ! But it will be good if the INPUT( command could accept CAS variable. Edited: 22 Aug 2013, 2:32 a.m. Re: Missing functions on the HP Prime!!!??? :-( - Eddie W. Shore - 08-22-2013 I agree, the INPUT command is very limited. I usually use pass-through arguments, (myfunc(a,b,c)) instead of INPUT. At least pass-through arguments allow various types of input. Re: Missing functions on the HP Prime!!!??? :-( - Gilles Carpentier - 08-22-2013 INPUT allows not only numbers but also also strings (between ""), matrices ( [[]]) , vectors, list etc ...
