MATLAB Object-Oriented Programming

function o = times(obj,val)

u8 = uint8(obj).*val;

o = DocUint8(u8);

end

When you override a uint8 method, MATLAB calls the subclass method, not the base

class method. The subclass method must:

• Call the uint8 times method on the DocUint8 object data.


• Construct a new DocUint8 object using the uint8 data.

After adding the times method to the DocUint8 class, the output of multiplication

expressions is an object of the DocUint8 class:

showImage(img1.*1.8);
