Write in in an editor file and save it as the title of function, e.g:

function hello_world(hObject,evt)
  fprintf(2,'Hello World!');
end

saved in hello_world.m

i simply copy this coding in command window but encounter errors in callback function.

[Walter Roberson]

Apply the solution Sean gave: write the sections that start with "function" into individual files.

The part before the first "function" line should be written into EZresize.m

then how can i connect these files to get the output

The message said so. You are not allowed to define a function in the command line or in a script file.

You need to create a separate .m file, where the first line, you define "function imageChoice_callback(hObject,eventdata)" and then save the file as imageChoice_callback.m.

Or, the function name sounds like belonging to a .m file for a GUI application. You should add this function in the .m file for that GUI application. The first line of that .m file should also be a "function ..." line. Otherwise, that .m file is called a script. You are not allowed to define a function in a script.
