divis(Poly
Returns the list of prime factors of a polynomial or a list of
polynomials. Each factor is followed by its multiplicity.
factors(Poly
Returns the greatest common divisor of two polynomials of
several .
gcd(Poly,Poly)
Returns the lowest common multiple of two polynomials of
several .
lcm(Poly,Poly))
With a variable as second argument, returns the coefficients
of a polynomial with respect to the variable. With a list of as
second argument, returns the internal format of the
polynomial.
symb2poly(Expr,[Var])
or
symb2poly(Expr,ListVar)
With one list as argument, returns a polynomial in x with
coefficients (in decreasing order) obtained from the list. With
a variable as second argument, returns a polynomial in the
variable as for one argument but the polynomial is in the
variable specified in the second argument.
poly2symb(Lst,Var)
Returns the coefficients (in decreasing order) of the univariate
polynomial of roots specified in the argument.
pcoef(Vect)
Returns the rational function that has the roots and poles
specified in the argument.
fcoeff(Lst(root||pole,order))
Returns a polynomial of variable specified in the first
argument, of degree n and where the coefficients are random
integers in the range −99 through 99 with uniform distribution
or according to the law specified in the third argument.
