Save and Load Objects

Use save and load to store and reload objects:

save filename object

load filename object

What Information Is Saved?

Saving objects in MAT-files saves:

• The full name of the object class, including any package qualifiers


• Values of dynamic properties


• All property default values defined by the class at the time the first object of the class
  is saved to the MAT-file.


• The names and values of all properties, with the following exceptions:
  
  
  • Properties are not saved if their current values are the same as the default values
    specified in the class definition.
  
  
  • Properties are not saved if their Transient, Constant, or Dependent attributes
    set to true.
  
  
  
  

For a description of property attributes, see “Specify Property Attributes” on page 8-7

To save graphics objects, see savefig.

NoteDo not use the pack command with objects that define events and listeners. The

pack command causes the destruction of any listeners defined for the objects in the
