0

dv = mp.DefaultValue;

No default value has been defined for property Foo

Abstract Property

MyClass defines the Foo property as Abstract:

classdef MyAbst

properties (Abstract)

Foo

end

end

The meta.property instance for property Foo has a value of false for its HasDefault

property because you cannot define a default value for an Abstract property. Attempting

to access DefaultValue causes an error:

mc = ?MyAbst;

mp = mc.PropertyList(1);

mp.HasDefault

ans =

0

dv = mp.DefaultValue;

Property Foo is abstract and therefore cannot have a default value.

Property with Expression That Errors

MyPropEr defines the Foo property default value as an expression that errors when

evaluated.

classdef MyPropEr

properties

Foo = sin(pie/2)

end

end
