MATLAB: Clim Change to help slider

Question

hello everyone do not know how slider can change the value Clim [0 b]. The property inspectr axes I have not found the box for the callback.

function varargout = books(varargin)
% Begin initialization code - DO NOT EDIT
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                 'gui_Singleton',  gui_Singleton, ...
                 'gui_OpeningFcn', @books_OpeningFcn, ...
                 'gui_OutputFcn',  @books_OutputFcn, ...
                 'gui_LayoutFcn',  [] , ...
                 '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 initialization code - DO NOT EDIT
function books_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = books_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;
function slider1_Callback(hObject, eventdata, handles)
set(handles.edit1,'String',...
  num2str(get(handles.slider1,'Value')));
I = imread('cameraman.tif');
imshow(I)
function slider1_CreateFcn(hObject, eventdata, handles)
if isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
  set(hObject,'BackgroundColor',[.9 .9 .9]);
end
function edit1_Callback(hObject, eventdata, handles)
val=str2double(get(handles.slider1,'Slider'));
  if isnumeric(val) & length(val)==1 & ...
          val >= get(handles.slider1,'Min') & ...
          vas <= get(handles.slider1,'Max')
          set(handles.slider1,'Value',val);
  else
          handles.numberOfErrors = handles.numberOfErrors + 1;
          set(handles.edit1,'CLim',...
          [handles.errorCLim,num2str(handsles.numberOfErrors)]);
          guidata(gcbo, handles);
  end
function edit1_CreateFcn(hObject, eventdata, handles)
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
  set(hObject,'BackgroundColor','white');
end

Answer 1

if I want to change only one parameter Clim help riders as I enter the second value that remained unchanged.

max_val = get(handles.slider1,'Value');
min_val = 256;
set(handles.axes,'CLim',[min_val. max_val],...
   get(handles.slider1,'Value'));
