Hi,
i wanna to edit 2 values in the GUI and with one button the simulnk gets these values and after the result should be displayed in the GUI.
but i dont understand set_param(). this is my code:
if true
function varargout = Gui(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name', mfilename, ...
'gui_Singleton', gui_Singleton, ...
'gui_OpeningFcn', @Gui_OpeningFcn, ...
'gui_OutputFcn', @Gui_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
% --- Executes just before Gui is made visible.
function Gui_OpeningFcn(hObject, eventdata, handles, varargin)
% Choose default command line output for Gui
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes Gui wait for user response (see UIRESUME)
% uiwait(handles.figure1);
% --- Outputs from this function are returned to the command line.
function varargout = Gui_OutputFcn(hObject, eventdata, handles)
% Get default command line output from handles structure
varargout{1} = handles.output;
function kraft_Callback(hObject, eventdata, handles)
kraft_value = str2num(get(hObject,'String'));
if (isempty(kraft_value))
set(hObject,'String','0')
end
guidata(hObject, handles);
function flaeche_Callback(hObject, eventdata, handles)
flaeche_value = str2num(get(hObject,'String'));
if (isempty(flaeche_value))
set(hObject,'String','0')
end
guidata(hObject, handles);
function start_Callback(hObject, eventdata, handles)
k = str2num(get(handles.kraft,'String'));
f = str2num(get(handles.flaeche,'String'));
set_param('Steifigkeit/k','String',num2str(k));
set_param('Steifigkeit/f','String',num2str(f));
set(handles.static,'String',spannung);
guidata(hObject, handles);
% --- Executes during object creation, after setting all properties.
function static_CreateFcn(hObject, eventdata, handles)
end
But i dont know what is the meaning of the parameters os set_param(). cann you help me pls?

Hi, I am trying to use set_param for changing 'Initial output' parameter of 'Ramp' block.
I am doing this by using:
global a1
set_param([bdroot '/BR-KT Assembly-1/Motion input2/Ramp1'],'Slope',a1)
But it gives me an error message saying: Error using GUI_Rohit>StartSimulation_Callback (line 429) Ramp block (mask) does not have a parameter named 'Initial output'
Can you suggest something to eliminate this?
Thanks a lot
Rohit

set_param allows to change any parameters block in your simulink model

You can use
get_param('Steifigkeit','Dialogparameters');

Sia: Not sure I understand your question. In this case, 'String' is the name of the parameter you are trying to set. Is that what you're asking?
