Hello my code gui can run passed but the error when this appear in my command window when i run my GUI.

that my code

function varargout = bebear(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @bebear_OpeningFcn, ...
                   'gui_OutputFcn',  @bebear_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
                   %'gui_Callback',   []);
    if nargin && ischar(varargin{1})
        gui_State.gui_Callback = str2func(varargin{1});
    end
      if nargout
          [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
      else
          gui_mainfcn(gui_State, varargin{:});
      end
  end
function bebear_OpeningFcn(hObject, eventdata, handles, varargin)
      get(eventdata)
      handles.output = hObject;
      guidata(hObject, handles);
  end
function varargout = bebear_OutputFcn(hObject, eventdata, handles) 
get(hObject)
get(eventdata)
      varargout{1} = handles.output;
  end
function browse_human_Callback(hObject, eventdata, handles)
get(hObject)
get(eventdata)
[filename pathname] = uigetfile({'*.jpg';'*.png'},'File Selector');
image = strcat(pathname, filename);
axes(handles.axes1)
imshow(image)
h = imline;
setColor(h,[1 0 0]);
%position = wait(h);
global posH
posH = getPosition(h)
end
function browse_bear_Callback(hObject, eventdata, handles)
get(hObject)
get(eventdata)
[filename pathname] = uigetfile({'*.jpg';'*.png'},'File Selector');
image = strcat(pathname, filename);
axes(handles.axes2)
imshow(image)
b = imline;
setColor(b,[1 0 0]);
%position = wait(h);
global posB
posB = getPosition(b)
end
function cal_CreateFcn(hObject, eventdata, handles)
end
function calculate_Callback(hObject, eventdata, handles)
tallH = str2double(get(handles.height_hu,'String'));
get(hObject)
get(eventdata)
global posH
global posB
sumH = posH;
sumhY1 =  posH(1,2);
sumhY2 = posH(2,2);
lineH = sumhY2 - sumhY1  
sumB = posB;
sumbY1 = posB(1,2);
sumbY2 = posB(2,2);
lineB = sumbY2 - sumbY1  
tallB = (tallH/lineH)* lineB
set(handles.height_bear, 'String', tallB)
end
function pic_CreateFcn(hObject, eventdata, handles)
get(hObject);
get(eventdata);
get(handles);
image = imread('bear.png');
imshow(image)
end

error massage:

??? Error using ==> feval
Undefined function or method 'height_bear_CreateFcn' for input arguments of type 'double'.
Error in ==> gui_mainfcn at 96
        feval(varargin{:});
Error in ==> bebear at 18
        gui_mainfcn(gui_State, varargin{:});
Error in ==>
@(hObject,eventdata)bebear('height_bear_CreateFcn',hObject,eventdata,guidata(hObject))
?? Error using ==> struct2handle
Error while evaluating uicontrol CreateFcn

how can I fix it

Tanachaporn - the error message is telling you that the function height_bear_CreateFcn cannot be found. Did you perhaps delete this function from your m file, or maybe rename it in the editor? In GUIDE, use the property editor to look at the CreateFcn for each of your controls to see which one has this function, and take the appropriate action. Else attach your GUI fig file so that we can see what is going wrong.

Hi error associated with the code is "Undefined function or method 'height_bear_CreateFcn' for input arguments of type 'double".

you dint mention the function height_bear in your designed gui so that if you write anything in that function means it will not run, because all the code in the main function will call from the gui and it will run, here in the designed gui there is no function related to height_bear, kindly insert that handles in your gui, so that your code will run
