Question

Is it possible to call a class method of all objects in a list?
Example:

    %my_objects contains a list of instances of the same user matlab class
    my_objects(:).my_func(42);

The purpose of this is to filter indexes instead of using “:”
Example:

    my_objects(1:10).my_func(42);

or

    my_objects(find(...)).my_func(42);

Answer 1

You can do so if you use arrayfun(), cellfun() or structfun(), depending on what “list” means.

Let’s assume it is an array (matrix), you can do

arrayfun(@(obj)obj.my_func(42), my_objects)

which iterates over my_objects and calls obj.myfunc(42) for each of the contained objects.
