coef double [] Vector of polynomial coefficients

[highest order ... lowest order]

The following table summarizes the methods for the DocPolynom class.

DocPolynom Class Methods

Name Description

DocPolynom Class constructor

double Converts a DocPolynom object to a double (that is, returns its

coefficients in a vector)

char Creates a formatted display of the DocPolynom object as powers

of x and is used by the disp method

disp Determines how MATLAB displays DocPolynom objects on the

command line

subsref Enables you to specify a value for the independent variable as a

subscript, access the coef property with dot notation, and call

methods with dot notation.

plus Implements addition of DocPolynom objects

minus Implements subtraction of DocPolynom objects

mtimes Implements multiplication of DocPolynom objects

Using the DocPolynom Class

The following examples illustrate basic use of the DocPolynom class.

Create DocPolynom objects to represent the following polynomials. The argument to the

constructor function contains the polynomial coefficients and

.

p1 = DocPolynom([1 0 -2 -5])

p1 =
x^3 - 2*x - 5

p2 = DocPolynom([2 0 3 2 -7])
