the syntax of a function could be summarized as:
[output1, output2, ...] = function(input1, input2, ...)
Say, yuor variable is named X in the function, then all you need to do is:
X = function(...)
If you call the function as:
your variable will be assigned automatically to ans, otherwise to
anyname = function(...)
anyname will be what is X in your function.
As Aldin pointed out, if you're in a GUI then use:

If you working in GUI i THINK that's impossible. It is an mistake in MATLAB because the data are not permanent as in Java.

Hi Oleg. Sorry for my behavior. Thank you. I didn't know that.I think It would be better for MATLAB to think object oriented.

I think "persistent" will help.
Just use
persistent variable_name = value

That is not valid syntax. You can use
persistent variable_name
to indicate that the variable keeps its value between calls. You cannot, though, initialize it in the same statement, and doing so would be a waste of the idea that you want to pull back the value the variable had in the last function call.
