What is the @ operator (at sign) in MATLAB?

Question

I have some MATLAB programs that use the @ (at sign) as an operator. What does it mean?

Does MATLAB 6.5 support this operator?

Answer 1

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.

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 it to be useful in Image Processing along with the "blockproc" command.

Actually, it is called a function handle (not handler) using similar naming convention as graphics objects also have 'handles'. – Disputatious

Answer 3

Documentation says that it's a function handle.
