## Class Polynomial: Multivariate polynomial

Instances of this class represent polynomials of any order and in any number of variables. They can be evaluated like functions.

Constructor: Polynomial(coefficients), where coefficients is an array whose dimension defines the number of variables and whose length along each axis defines the order in the corresponding variable. The coefficients are ordered according to increasing powers, i.e.\ [1., 2.] stands for 1.+2.*x.

Methods:

- derivative(variable=`0`)

  Returns the derivative with respect to variable.

- integral(variable=`0`)

  Returns the indefinite integral with respect to variable.

- zeros()

  Returns an array containing the zeros (one variable only).
