MATLAB Object-Oriented Programming

level = PPM.High;

When you substitute enumeration members for instances of the superclass, MATLAB

coerces the enumeration member to the superclass. For example, add an enumeration

member of the PPM class with a numeric values

levelNew = level + 100

levelNew =

1100

The result is of class double.

level 1x1 108 PPM

levelNew 1x1 8 double

You can substitute superclass values for enumeration members when the values

correspond. For example, pass one of the numeric values defined in the enumeration class

to the PPMSwitch function.

function PPMSwitch(ppm)

switch ppm

case PPM.Low

disp Low

case PPM.Medium

disp Medium

case PPM.High

disp High

end

end

PPMSwitch(100)

Medium

You can also use an enumeration member directly:

PPMSwitch(PPM.Medium)

Medium
