Functions and commands

Special

Cyclotomic

Returns the list of coefficients of the cyclotomic polynomial of

an integer.

cyclotomic(Integer)

Example:

cyclotomic(20)

gives [1 0 –1 0 1 0 –1 0 1]

Groebner Basis

Given a vector of polynomials and a vector of variables,

returns the Groebner basis of the ideal spanned by the set of

polynomials.

gbasis([Poly1 Poly2…], [Var1 Var2…])

Example:

gbasis([x^2-y^3,x+y^2],[x,y])

returns

[y^4-

y^3,x+y^2]

Groebner

Remainder

Given a polynomial and both a vector of polynomials and a

vector of variables, returns the remainder of the division of the

polynomial by the Groebner basis of the vector of

polynomials.

greduce(Poly1, [Poly2 Poly3 …], [Var1
Var2…])

Example:

greduce(x*y-1,[x^2-y^2,2*x*y-y^2,y^3],[x,y])

returns

1/2*y^2-1

Hermite

Returns the Hermite polynomial of degree n, where n is an

integer less than 1556.

hermite(Integer)

Example:

hermite(3)

gives

8*x^3-12*x
