Convert DocPolynom Objects to Other Types

The DocPolynom class defines two methods to convert DocPolynom objects to other
classes:

• double — Converts to the double numeric type so functions can perform
  mathematical operations on the coefficients.


• char — Converts to characters used to format output for display in the command
  window

The Double Converter

The double converter method for the DocPolynom class simply returns the coefficient
vector:

methods
function c = double(obj)
c = obj.coef;
end
end

For the DocPolynom object p:

p = DocPolynom([1 0 -2 -5]);

the statement:

c = double(p)

returns:

c=
1 0 -2 -5

which is of class double:
