MATLAB Object-Oriented Programming

Example Code Discussion

function m = get.Modulus(obj)

ind = find(obj.Strain > 0);

m = mean(obj.Stress(ind)./obj.Strain(ind));

end

Calculate Modulus property when

queried.

For information about this code, see

“Modulus Property Get Method” on page

3-23.

For general information about property

get methods, see “Property Get Methods”

on page 8-60.

function obj = set.Modulus(obj,~)

fprintf('%s%d\n','Modulus is: ',obj.Modulus)

error('You cannot set Modulus property');

end

Add set method for Dependent Modulus

property. For information about this code,

see “Modulus Property Set Method” on

page 3-24.

For general information about property

set methods, see “Property Set Methods”

on page 8-56.

function disp(td)

fprintf(1,'Material: %s\nSample Number: %g\nModulus: %1.5g\n',...

td.Material,td.SampleNumber,td.Modulus)

end

Overload disp method to display certain

properties.

For information about this code, see

“Displaying TensileData Objects” on page

3-24

For general information about

overloading disp, see “Overloading the

disp Function” on page 18-42

function plot(td,varargin)

plot(td.Strain,td.Stress,varargin{:})

title(['Stress/Strain plot for Sample',...

num2str(td.SampleNumber)])

ylabel('Stress (psi)')

xlabel('Strain %')

end

Overload plot function to accept

TensileData objects and graph stress

vs. strain.
