MATLAB: Loading MAT file problem

neural network

When loading a mat file (trained nn) in R2010b the following error warning is shown:

QUOTE

>> load('netAantalMosselen.mat') Warning: An error occurred when running a class's loadobj method. The object that was loaded from the MAT-file was a copy of the object before the loadobj method was run. The rest of the variables were also loaded from the MAT-file. The encountered error was: Reference to non-existent field 'name'.

UNQUOTE

Loading the same mat file in R2007b does not show this message. BtW The mat file value in the 2010b workspace is struct and not network.

Can some explain what is happening here? Thanks in advance

The customer received a fixed net.m file and confirmed it works now. If you see this issue in the future, please contact Technical Support and refer to solution 1-EGNM3S.

MATLAB: Do I receive a “Error loading an object of class ‘proplistener'” warning when I LOAD the object that has an event listener in MATLAB 7.7 (R2008b)

The cause of the warning message is that while loading the object from the MAT-File, MATLAB was not able to attach the listener back to the object. If you check for 'proplist' property of the loaded object, you will find it is empty.

A listener object is attached to the object as long as the object remains in scope. Once you save the object it goes out of scope, so the listener for the saved object is destroyed. In order to keep the listener with the object as it is saved and loaded back into the workspace, you will need to define the LOADOBJ and SAVEOBJ functions in your class definition file.

Please refer to the Help documentation on SAVEOBJ and LOADOBJ by typing the following at the MATLAB Command Prompt:

 doc saveobj
 doc loadobj
