This command works in CAS View only.
- RandomPolynomial[ <Degree d> , <Minimum for Coefficients min>, <Maximum for Coefficients max> ]
- Returns a randomly generated polynomial in x of degree d, whose (integer) coefficients are in the range from min to max, both included.
- Example:
RandomPolynomial[0, 1, 2]yields either 1 or 2 andRandomPolynomial[2, 1, 2]yields a random polynomial with a degree of two and only 1 and 2 as coefficients, for example 2x2 + x + 1.
- RandomPolynomial[ <Variable Var>, <Degree d> , <Minimum for Coefficients min>, <Maximum for Coefficients max> ]
- Returns a randomly generated polynomial in Var of degree d, whose (integer) coefficients are in the range from min to max, both included.
- Example:
RandomPolynomial[a, 0, 1, 2]yields either 1 or 2 andRandomPolynomial[a, 2, 1, 2]yields a random polynomial with a degree of two and only 1 and 2 as coefficients, for example 2a2 + a + 1.
Note: In both cases if min or max are not integers, round(min) and round(max) are used instead.
