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.

范例：

• RandomPolynomial[0, 1, 2] yields either 1 or 2 and
• RandomPolynomial[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.

范例：

• RandomPolynomial[a, 0, 1, 2] yields either 1 or 2 and
• RandomPolynomial[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.

备注： In both cases if min or max are not integers, round(min) and round(max) are used instead.
