Re: Did I miss something about structures and function handles

[James Sherman Jr.]

I think he means if the structure has fields, xx, yy, and f, something like
b.xx = 10;
b.yy = 7;
could he write a function f like this:
b.f=@(X)(xx+yy+X)

where xx and yy refer to the other fields in the b structure (something like this->xx if this was in C++), which I don't think is possible in octave.  But I don't have a good grasp of what OOP really and truly means, so the 90% of OOP comment by kensmith confuses me.  I usually think of it in terms of could be done in C (not OOP) vs. C++ (is OOP), but everything kensmith wrote in his email seems to not be OOP to me.  It is just a struct with a field that is a function (or function pointer).  I could be way off base though.

Which 'other elements' of b and c do you mean? In your example above,
I can see only one element (a) in b and c.
