Answer 1

Documentation says that it's a function handle.

Answer 2

It used to declare Anonymous Functions in Matlab.

I think the terms is "Function Handle".

Practically it covers the inability of Matlab to declare a function at any place in any M file.

I found t to be useful in Image Processing along with the "blockproc" command.

Answer 3

The @ operator creates a function handle, something that allows you to easily create and pass around a function call like a variable. It has many nice features, none of which are available to you unfortunately. This is because as you suspect, it was not introduced into matlab until version 7, the release immediately after yours.
