How can I pass Axes (GUI) into a function

I am designing a function that is supposed to show a picture on an axes if a certain if condition is satisfied. eg:

%GUI PUSHBUTTON CALLBACK

function PushButton_Callback(hObjects,eventdata,handles)
while(1)
  Image1 = imread('image1.png')
  Image2 = imread('image2.png');
  Out_Fun = MyFun (Image1,Image2,axes1); %axes1 is a drawn axes in the GUI
end
 ---------------------------------
%MyFunction

function [Output] = MyFun (Image1,Image2,axes1)
  corr = corr2(Image1,Image2);
      if (corr == 1)
         axes(handles.axes1)
         imshow('SAME FIG.png');
      else
         axes(handles.axes1)
         imshow('NOT SAME FIG.png');

So my question is how can I pass the axes1 handle to MyFun so that I can use it inside the function

by handles

function []=yourfunction(handles,...)

Works like a charm. Thanks

In your above code, you don't pass the handles structure when you call "MyFun." Therefore, you wont be able to access your axes through the handles structure because "handles" doesn't exist in the workspace of that function. To fix this, the easiest thing to do would be to change your function to:

function [Output] = MyFun(handles,Image1,Image2)
 corr = corr2(Image1,Image2);
    if (corr == 1)
       axes(handles.axes1)
       imshow('SAME FIG.png');
    else
       axes(handles.axes1)
       imshow('NOT SAME FIG.png');

Then, you can call it with:

Out_Fun = MyFun (handles,Image1,Image2);

Another option, I believe, would be to leave your function definition as it is but change the instances of "handles.axes1" to just "axes1."
