Example Code Discussion
function obj = DocPolynom(c)
if nargin > 0
if isa(c,'DocPolynom')
obj.coef = c.coef;
else
obj.coef = c(:).';
end
end
end
Class constructor creates objects
using:
- Coefficient vector of existing
object - Coefficient vector passed as
argument
See “The DocPolynom
Constructor” on page 19-13
function obj = set.coef(obj,val)
if ~isa(val,'double')
error('Coefficients must be doubles')
end
ind = find(val(:).'~=0);
if ~isempty(ind);
obj.coef = val(ind(1):end);
else
obj.coef = val;
end
end
Set method for coef property:
- Allows coefficients only of
type double - Removes leading zeros from
the coefficient vector.
See “Remove Irrelevant
Coefficients” on page 19-14
function c = double(obj)
c = obj.coef;
end
Convert DocPolynom object to
double by returning the
coefficients.

Objects to Other Types” on page
