From: Yao Konan on 31 Aug 2006 16:21 Thanks. There is some others code that you can try such as this one: Define keynum()=Func: Local key: 0->key: While key=0: getkey()->key: EndWhile: return key: EndFunc This function enables to get the code of a key. Btw do you know if the TI-NSpire support variables of more than 8 characters and folder within Problems ? Michael Kuyumcu a écrit : > Hi, > > I am very grateful to your effort and help! It works!

From: Yao Konan on 31 Aug 2006 16:24 If it is possible to plot 3D graph this command should enabe it,if the NSpire behaves like the TI92: setmode("Graph","3D"):Graph (x^3*y-y^3*x)/390 Michael Kuyumcu a écrit : > Is there a quick way to test 3D functions plotting capabilities.

Well,i think that those 32 MB are Flash ROM as the TI site claims that the TI-NSpire has close to 20 MB of storage memory thus Flash ROM. The TI site also claims 16 MB of computing memory so iassume that this memory is not SRAM and can't be used to store datas. > Interesting: fib(10000) produces an overflow, even in Exact mode, while > the CAS seems to be capable of handling multiple-precision numbers > otherwise with no problems.fib(1000) works, and does so within 2 > seconds. Surprising. That would mean that the TI-NSpire is more than 10 times faster than my TI92+ on this problem.This is simply incredible ! To have a better idea of the relative speed of this tool could you clock this operation which takes almost 4 min on a TI92+ ? approx(randmat(20,20)^-1) It doesn't really suprise me that fib(10000) returns an overflow. > Regards, > Michael Kuyumcu > > >
