|MATLAB Function Reference|
Save an object to a MAT-file
B = saveobj(A)
is called by the MATLAB
save function when object,
A, is saved to a .MAT file. This call executes the
saveobj method for the object's class, if such a method exists. The return value B is subsequently used by
save to populate the .MAT file.
When you issue a
save command on an object, MATLAB looks for a method called
saveobj in the class directory. You can overload this method to modify the object before the save operation. For example, you could define a
saveobj method that saves related data along with the object.
saveobj can be overloaded only for user objects.
save will not call
saveobj for a built-in datatype, such as
double, even if
saveobj will be separately invoked for each object to be saved.
A child object does not inherit the
saveobj method of its parent class. To implement
saveobj for any class, including a class that inherits from a parent, you must define a
saveobj method within that class directory.
The following example shows a
saveobj method written for the
portfolio class. The method determines if a
portfolio object has already been assigned an account number from a previous
save operation. If not,
getAccountNumber to obtain the number and assigns it to the
account_number field. The contents of
b is saved to the MAT-file.
