Dear Bernard,
I'm studying how it is possible to use your library for the
factorization.
I have some of questions:
1) I want to install only the necessary libraries for my aims.
I already have GMP and NTL and so I think would be enough
GIAC in order to the factorization on rationals, is it true?
(I do not work with floating point numbers and I am not interested
on graphic's tools.)
The installation's process is finished well, even if I have again
a doubt: what is DL support which by default is setted to `yes'?
2) The second question is about the input of an object of the type
`gen':
in the little program attached you can see that the use of `n*5'
instead of `5*n' caused an ambiguity for operator*.
It seems very strange for me this behavior... Is it wanted?
Thanks in advance, all the best
Tatiana Zolo
#include <giac/giac.h>
using namespace std;
using namespace giac;
int main() {
identificateur h("h");
identificateur n("n");
#if 1
gen p = pow(h,4)+pow(h,3)*(2*n+4)+pow(h,2)*(pow(n,2)+5*n+5)
+h*(pow(n,2)+3*n+2);
#else
gen p = pow(h,4)+pow(h,3)*(2*n+4)+pow(h,2)*(pow(n,2)+n*5+5)
+h*(pow(n,2)+3*n+2);
#endif
gen q = factor(p);
cout << p << " -> " << q << endl << endl;
return 0;
}
