MATLAB equivalent to Java's {}

Question

I'd like to know MATLAB's equivalent to Java's {} for delimiting code blocks. It seems that it would be simple to find out such a thing, but it is hard to search {} on Google, so I turn to StackOverflow. Thanks for the help!

EDIT: My goal is to define a multi-line anonymous function.

What is it you want to achieve? Local scope variables, code folding for easy editing? — angainor, Sep 25 '12 at 17:45

You can define a sub-function in the same file to do that:

function y=foo()
  y=1;
  bar(y)
end

function z=bar(y)
  x=2*y; % x stays local
  z=2*x;
end

The problem with this on the other hand is that you can not define functions in simple scripts. That's why foo needs to be a function. – angainor Sep 25 '12 at 18:06

You can use ... to continue lines. So to make a multi-line anonymous function:

fun=@(x)(...
    x.^2+...
    x+...
    1);

fun(1:10)

ans =

 3     7    13    21    31    43    57    73    91   111

If on the other hand you want to have multiple statements in an anonymous function, it is not possible. See e.g. this other SO post.

lol, that actually is multi-line. But he meant anonymous function with serveral instructions (e.g x=2;y=3;z=x*y;). – Oli Sep 25 '12 at 18:04
@Oli well, I just answered the question :) Thats why I asked to make it more precise.. – angainor Sep 25 '12 at 18:05
