If you have static parameters which you do not want to change through out the program, you can declare them in OpeningFcn callback of GUI.

Everytime you open the GUI, these parameters are set.

function untitled1_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to untitled1 (see VARARGIN)
handles.f=3.5;      
handles.pt=40;      
handles.pr=27;     
handles.n=6;        
handles.ht=5;    
handles.hr=0.005;  
% Choose default command line output for untitled1
handles.output = hObject;

% Update handles structure
guidata(hObject, handles);

how to call them in other functions, can you give examle of the syntax ?

[Ajay Kumar]

For calling the variables, you need to get these handles as the parameters for the function.

For example:

function sample_function(hObject, eventdata, handles, ...%some more user defined if you want )
    % do something
    % you can call your handles variables here directly.  for eg: x = handles.f + 1;
end
