Hi all,
i just downloaded a matlab function from some website and saw something strange
if ~isa(A, 'function_handle')
AT = @(x) A'*x;
A = @(x) A*x;
end
what is the meaning of @?

An anonymous function is like an inline function in traditional programming languages, defined within a single MATLAB statement. It consists of a single MATLAB expression and any number of input and output arguments.
You can define an anonymous function right at the MATLAB command line or within a function or script.
This way you can create simple functions without having to create a file for them.
The syntax for creating an anonymous function from an expression is
f = @(arglist)expression

I have no idea what point you're trying to make but note that you started talking about anonymous function, your new comment demonstrates function handles which are not the same as anonymous functions (despite both using the symbol @)
