Russian translation

Hi Vadim.

I develop a script (texi.sh) using shell and sed that allow to you type  in 
your native language. After you end the translation file you load the script 
and its convert the diacritical marks in your language to texinfo code.

I am a lot of panic with myself to say that i only use this script with two 
least translated files of Maxima manual and to say that the other 30 files 
was translated without it. 

Need to be changed by russian language

Hope that this make easy your translation.

Another Uper / lower case question.

I am testing in windows XP

Maxima version: 5.9.1.9rc3
Maxima build date: 23:21 9/27/2005
host type: i686-pc-mingw32
lisp-implementation-type: GNU Common Lisp (GCL)
lisp-implementation-version: GCL 2.6.7

At the start up screen, in the lower panel, there is a reference to 
examples:
"There are examples which you may also look at 3d plotting  If you "

when I click on examples it bring up a new page that looks like:
Demo programs

        Example( "//" )
        Example( ADDITIVE )
        Example( ALGSYS )
        Example( ALLROOTS )
        Example( ANTISYMMETRIC )
        Example( APPEND )
        Example( ARRAYINFO )

etc.

These all have upper case letters, and therefore don't run when you 
click on them.

I hope this is helpful.

I can't get any result for the first one.

Re: An example problem.

hi doug,

> I can't get any result for the first one.
>         example( "//" )

this is a pretty obscure bug -- the example is for a function
named rat, and "//" is the result of attempting to dollarify the
symbol RAT using $CONCAT. i think MAKEALIAS is more
appropriate. (as i was saying it's quite obscure.)

if MAKEALIAS fixes it, then i'll roll it into the next release
candidate, otherwise, it will get fixed later.

thanks for pointing out this problem. i appreciate your help a lot!

polynomial interpolation

Hi,

it looks like Maxima doesn't have any polynomial interpolation support,
am I wrong ? In a software like Pari/GP, there is :

> ?polinterpolate
polinterpolate(xa,{ya},{x},{&e}): polynomial interpolation at x according to
data vectors xa, ya (ie return P such that P(xa[i]) = ya[i] for all i). If ya
is omitter, return P such that P(i) = xa[i]. If present, e will contain an
error estimate on the returned value.

> polinterpolate([0,1,4,9,16,25,36])
%45 = x^2 - 2*x + 1

Is there really nothing like that in Maxima ?

Regards,

Please, see the following Maxima session.

Hope it helps.

(%i2) /* define Lagrange interpolation  */
lagrange(tab) := block([n:length(tab),sum:0,prod],
   for i:1 thru n do(
      prod: 1,
      for k:1 thru n do
         if k#i then prod: prod * ('x-tab[k][1]) / (tab[i][1]-tab[k][1]),
      sum: sum + prod * tab[i][2] ),
   ratsimp(sum) )$

(%i3) /* empiric data */

question about partfrac

partfrac (  +3 /(s^2 +6*s +8.2),s) ;

Since this has 2 real roots I would expect two terms in the answer but I 
get only 1.
how do you make it give the two terms?

Re: question about partfrac


Partfrac solves a given problem over the rational numbers,
not the (approximate) real numbers.

If you really want the (numeric, approximate) partial
fraction expansion, that can be computed, but partfrac doesn't do that.

See note below yours, for a program, fpfe, that does this.

(C8) fpfe(d1,s);
		   1.677050983124843	   1.677050983124843
(D8) 		 --------------------- - ---------------------
		 s + 2.105572809000084	 s + 3.894427190999916
(C9)
.... keepfloat:true$
ratsimp(d8); gives
almost the same as what you started with.
But not exactly.
RJF

PS, as far as I know, this is not in the "share" directory. But
it could be put there. LLGPL.
