Enumerations in switch Statements

Equality (eq) and inequality (ne) methods enable you to use enumeration members in

switch statements. For example, using the WeekDays class defined previously, construct

a switch statement:

function c = Reminder(day)

% Add error checking here

switch(day)

case WeekDays.Monday

c = 'Department meeting at 10:00';

case WeekDays.Tuesday

c = 'Meeting Free Day!';

case {WeekDays.Wednesday WeekDays.Friday}

c = 'Team meeting at 2:00';

case WeekDays.Thursday

c = 'Volleyball night';

end

end

Pass a member of the WeekDays enumeration class to the Reminder function:

today = WeekDays.Wednesday;

Reminder(today)

ans =

Team meeting at 2:00

Substitute char Vectors

NoteEnumeration classes that derive from MATLAB built-in classes cannot substitute

char vectors for enumeration members.
