MATLAB Object-Oriented Programming

Low (10)

Medium (50)

High (100)

end

end

Reference an instance of an enumeration member:

setFlow = FlowRate.Medium;

This statement causes MATLAB to call the default constructor with the argument value of

50. MATLAB passes this argument to the first superclass constructor (int32(50) in this

case). The result is an underlying value of 50 as a 32-bit integer for the

FlowRate.Medium member.

Because FlowRate subclasses a built-in numeric class (int32), this class cannot define

properties. However FlowRate inherits int32 methods including a converter method.

Programs can use the converter to obtain the underlying value:

setFlow = FlowRate.Medium;

int32(setFlow)

ans =

50

Default Converter

If an enumeration is a subclass of a built-in numeric class, you can convert from built-in

numeric data to the enumeration using the name of the enumeration class. For example:

a = Bool(1)

a =

Yes

An enumerated class also accepts enumeration members of its own class as input

arguments:

Bool(a)
