I am using Matlab 2007b and get the following error:

Exception in thread “AWT-EventQueue-0″ java.lang.OutOfMemoryError: GC overhead limit exceeded.
And another one concerning java-heapspace.
There is no bug in the program, since on a linux-workstation it works well. But on a plain Windows machine (java 1.5 / 1.6) I get this messages.
How do I handel java memory issues under Matlab 7.5 ??

Thanks a lot.

The short answer is, not easily. persistent requires variable and n.Input is a temporary variable since it is a field in a struct or object. You could have a persistent variable in your constructor and then assign its value to a field in the object. Or you could have some state in your object by storing your “persistent” variable in the constructor where the constructor uses nested functions to preserve state. There is a relatively new example on the File Exchange that does something similar: http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=17240&objectType=FILE

is there a way to work with variables that belong to a class rather than to an instance of a class ?
In Java I would write “private static” inside the class definition. I tried it with “persistent”, but Matlab doesnt like constructions like: “persistent n.Input” e.g. inside the constructor with n being my object.

Thanks for your help,
Martin.

You’d be better off contacting technical support for issues about Simulink. Here’s the link:

Here’s a quick anonymous function:

c1contents = @(c) c{1}

>> s = {'fred'}
s =
    'fred'
>> c1contents(s)
ans =
fred
>> c1contents({2})
ans =
     2
>> c1contents({1 4 17})
ans =
     1

You could use char() if you know A is a single string, either in a cell or not. But it doesn’t work for numeric types. Would that help?
