Example:

randpoly(t, 8, -1..1) returns a vector of 9 random integers, all of them between –1 and 1.

Minimum

With only a matrix as argument, returns the minimal polynomial in x of a matrix written as a list of its

coeicients. With a matrix and a variable as arguments, returns the minimum polynomial of the matrix

written in symbolic form with respect to the variable.

pmin(Mtrx,[Var])

Example:

pmin([[1,0],[0,1]],x) gives x-1

Polynomial – Algebra

Quotient

Returns a vector containing the coeicients of the Euclidean quotient of two polynomials. The polynomials

may be written as a list of coeicients or in symbolic form.

quo(List1, List2, [Var])

quo(Poly1, Poly2, [Var])

Example:

quo({1, 2, 3, 4}, {-1, 2}) returns [-1 -4 -11]

Remainder

Returns a vector containing the coeicients of the remainder of the Euclidean quotient of two polynomials.

The polynomials may be written as a list of coeicients or in symbolic form.

rem(List1, List2, [Var])

rem(Poly1, Poly2, [Var])

Example:

rem({1, 2, 3, 4}, {-1, 2}) returns [26]

Degree

Returns the degree of a polynomial.

degree(Poly)

Example:

degree(x^3+x) gives 3

Factor by Degree

For a given polynomial in x of degree n, factors out xn and returns the resulting product.

factor_xn(Poly)
