Poly

Creates a polynomial.

Syntax:

f := Poly(A, L);

polynomial
  f  
polynomial algebra
  A  
list
  L  

See also:  PolyAlg

Description:

Given a polynomial algebra A and a list of elements (coefficients) L:=[c_n, c_{n-1}, … ,c_0] the function returns the polynomial f(x):=\sum_{i=0}^n c_i x^i. The c_i must be elements of the coefficient ring of A.


Example:

Creation of the polynomial x^5 + 2*x^4 + 3*x^3 + 4*x^2 + 5*x + 6\inZ[x]:

kash> f := Poly(Zx, [1, 2, 3, 4, 5, 6]);
> x^5 + 2*x^4 + 3*x^3 + 4*x^2 + 5*x + 6
