ode::polynomialSolutions

Polynomial solutions of a homogeneous linear ordinary differential equation

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Syntax

ode::polynomialSolutions(Ly, y(x), <Generic>)

Description

ode::polynomialSolutions computes a fundamental set of polynomial solutions of a homogeneous linear ordinary differential equation.

ode::polynomialSolutions returns a fundamental set of the polynomial solutions of Ly, i.e., solutions in the ring . When the option Generic is given, a generic form of them is returned.

Examples

Example 1

We compute the polynomial solutions of the following differential equation:

Ly:=3*x*diff(y(x),x,x)-x*diff(y(x),x)+9*y(x)

ode::polynomialSolutions(Ly, y(x))

ode::polynomialSolutions(Ly, y(x), Generic)

Parameters

Ly

A homogeneous linear ordinary differential equation with coefficients in the field (x) of rational functions over the rationals.

y(x)

The dependent function of Ly.

Return Values

set, possibly empty, of functions or an expression
