Create an array of VerySimpleClass objects:
vsArray(1:10) = VerySimpleClass;
The Value property for array elements 2 through 10 is empty:
isempty([vsArray(2:10).Value])
ans =
1
MATLAB does not apply scalar expansion to object array property value assignment. Use
the deal function for this purpose:
[vsArray.Value] = deal(1:10);
isempty([vsArray.Value])
ans =
0
The deal function assigns values to each Value property in the vsArray object array.
Indexing rules for object arrays are equivalent to the rules for arrays of struct:
vsArray(1).Value
ans =
1 2 3 4 5 6 7 8 9 10
vsArray(1).Value(6)
ans =
6
Change the Behavior of size or numel
Subclasses of built-in numeric classes inherit a size method, which operates on the
superclass part of the subclass object (these methods are hidden). If you want size or
numel to behave differently, override them by defining a size or numel method in your
subclass.
Use of size and numel with Classes
