Basic Knowledge

See the save and load functions and “Save and Load Process for Objects” on page 13-2

for general information on saving and loading objects.

To see a list of enumeration names defined by a class, use the enumeration function.

Built-In and Value-Based Enumeration Classes

When you save enumerations that derive from built-in classes or that are value-based

classes with properties, MATLAB saves the names of the enumeration members and the

definition of each member.

When loading these enumerations, MATLAB preserves names over underlying values. If

the saved named value is different from the current class definition, MATLAB uses the

value defined in the current class, and then issues a warning.

Simple and Handle-Based Enumeration Classes

When you save simple enumerations that have no properties, superclasses, or values

associated with the member names or enumerations derived from the handle class,

MATLAB saves the names and any underlying values.

When loading these types of enumerations, MATLAB does not check the values associated

with the names in the current class definition. This behavior results from the fact that

simple enumerations have no underlying values and handle-based enumerations can

legally have values that are different than those values defined by the class.
