Indexing an Object with Another Object

When MATLAB encounters an object as an index, it calls the subsindex method defined for the object. For example, suppose you have an object a and you want to use this object to index into another object b.

```
c = b(a);
```

A subsindex method might do something as simple as convert the object to double format to be used as an index, as shown in this sample code.

function d = subsindex(a)
%SUBSINDEX 
% convert the object a to double format to be used
% as an index in an indexing expression
d = double(a);

subsindex values are 0-based, not 1-based.
