MATLAB: Callback function

function callback script

Hi all,
I am trying to implement a piece of code (a function) into my script. The original code comes from a function. Running my script gives me the following error:
Error: Function definitions are not permitted in this context.
So I put a function declaration in a script, which is causing the error.
I tried putting the function in a seperate function file, but the function needs some variables that are used in the script. So provide the functions with some in- and output variables. But that's the part I am stuck. The functions is called by a callback, and I can't seem to add variables to it. Here is the piece of code which calls the function:
htimes1 = uicontrol( 'Style', 'pushbutton', 'String', '* ',  'Callback', {@bpmaall_Callback});
The function associated with this callback is:
function bpmaall_Callback(source, eventdata)
      assenbp=ylim;
      assenfft=xlim;
      deltaxas1=0.05*assenbporg;
      ynewbp= assenbp(2)-deltaxas1;
      plot(frequency(1:80),fftsysbp(1:80),'r')
      axis([0 assenfft(2) 0 ynewbp])
end
Does someone know a way to avoid this problem?
The piece of code is used to change the y-axis when a button is pressed. Any help is welcome.

    You need
... 'Callback', {@bpmaall_Callback,x,y,uv});%no ()
