 If you were me and needed to choose a gift for a geek friend (who likes beer) which one would you choose? Thank you (=

Well, is know for anyone who uses an nspire that is some kind of matrix for store each function/program/var on the nspire's documents.
I was wondering about changing all funcions to libpub in a document and there's a lot of them, so I thought if was possible to do a program for doing this...
Well, If is possible (somehow) to change information in the "getvarinfo()" matrix, it would be very easy as is just to change the third column to "LibPriv", however if not, I have no clue how to change a library while in a program (neither if it is possible to do so).
Any help will be appreciated, even nggyp if you post the reply on the youtube comments

I know that there is a sample from TI, that shows that it's possible.
But I couldn't really understand that file riemann.lua
Does anyone know how I can I do it, or know a better example for understanding.this?
I just need a calculation sheet, so the user can input a function e.g. define f2(abobora)=1/abobora!

Well, I am trying to do a small program [sorry guys, but isn't a game] it is for testing the convergence of series..
And I was wondering if I could do this in a colorful, and beautiful way with lua, but, is possible to call a TI-Basic program within lua code:
I mean like:
function convergence.power()
callmyBasicPrgm()
end
or if possible:
function convergence.power()
Local rterm,aterm,sumv
:clrio
:Try
:lim((equ(x))^(((1)/(x))),x,∞,1)→rterm
:Else
:If errornum=800 Then:
:(...)
:Return 0
end

Well, I was doing some easy algorithm (frobenius method);
and I got an issue, I have a list like this: {a0+6*a1,a1+20*a2,a2+42*a3,a3,...}
And I must get it solved in terms of a0;
I can do this with: solve(list[1]=0 and list[2]=0 and list[3]=0 ...,a1,a2)
and the return is:
a1=−a0/6 and a2=a0/120 and a3=−a0/5040...
The question is can I store those "results" in a list? //sorry if is a dumb question but I couldn't find any example of this.
EDIT:
Someone know how to use variadic functions/programs like:
median(List[,freqlist])
?
// Nspire CAS 1.7 [this is the only version I can have working in computer for free besides ncubate]

I got this buggy "Program": The program cannot evaluate that bolded line, however, I can calculate this : desolve_h(exp2vector(fx,y,x),x)//Nspire OS 1.6

I don't know If any of you had a similar situation to this one, but I really need help as this could be a way to get a Nspire CAS Cx. I bought two calculators at http://underwooddistributing.com/And then they when they site calculated the shipment it said it would be $3 (usd) for bringing it here [Brazil]. Then, I got this e-mail today: My question is: If their site made this calculation wrong isn't their problem and they should give me the product, or they may not sell this to me? Because I feel cheated by this whole system.  Sometime ago, I bought a book from a danish site, and it made the shipment calculation wrong too, but they assumed it was their error, corrected their site, and send me the product.  So I was wondering how does this work on the USA... Can anyone help me?

I know it hasn't been a long time since my last post, but
as this is another subject I thought it was better to make a new one...
I was trying to make define a function again, for dont have many functions in the calculator
but I got this error: "To many recursions", and display "Define f2(x)=((f2(x))/(x-raiz))"
: If a≠grau Then
: Define f2(x)=((f2(x))/(x-raiz))
Now I was wondering if is possible to create functions like f3 ... on demand like
Define f(x)=x...
Thanks, for any help regarding this.

Suppose you have a function like Define a(Expression,[varlist],[varerror])=Func ... How can I know how many terms the user used between each [] ? I know that, if was a list such as a(expr,{varlist},{varerror})=func I could do: newMat(dim(varlist),1) but with this workaround I can't re-use the function ... as the output would be in the format[], and the input is a list ..  Thanks for read this topic, and especially if can clarify how to do this!!

Well, I was just looking at some google pages ...
and saw at least 3 Nspire CAS+ for sell in some sites [including ebay]
I know it isn't upgradable [in theory] to the new OSes
but, it still much cheaper than almost every other calculator with similar functions such as taylor() among others.
So my question is: Is it worth to pay 170 BRL =~[100 USD] =~ [80 euros] for it?
It would be for college study.
And another question, but this I think will not be easy to reply as only someone with it could try ...
How 'impossible' is to upgrade it's OS?

 If you do not want to click here in the image you can go to the link: http://tinyurl.com/KylloAppealYou may click, it is a very seriously appeal to the Calc community. [I am not asking for money - {I would like if you give me some, but it's not the point}]

I kind like nsolve [as solve isn't in my calc  ] but it don't show all solutions, so I tried to do this: Define LibPub nsolver(eq,x)=
Prgm
:Local a,b,c
:a:=−100
:b:=nSolve(eq,x=−100)
:Disp "Solutions: "
:Disp b
:While a≤100
: a:=a+1
: c:=nSolve(eq,x=a)
: If b≠c Then
: Disp c
: b:=c
: EndIf
:EndWhile
:EndPrgm
It actually does work, but not as wished I typed this: nsolver((x^(2)+4*x-2)*(x+9)*x=0,x) I got this as output: Solutions: −9. −4.44949 −4.44949 0. 0.44949 0.44949 Look at the code, how can the same output be displayed twice?

Well, maybe it would improve people to learn asm, and also help some to improve their productivity ...
I don't mean exactly like HLA, but a standard library with HL for the actual process.
