Hey, basicly I made a gui with 3 inputtext fields and a button. When pressing the button it should put the data from the input field into a variable and then start a function with these variables. If i declare the variables with just a regular variable it seems to work.(see commented example) How do i read the edittext?
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
disp('start running code');
handles = guidata(hObject);
var1 = get(handles.edit1, 'string');
var2 = get(handles.edit2, 'string');
var3 = get(handles.edit3, 'string');
%var1 = 2;
%var2 = 0.5;
%var3 = 300;
freessimulatie(var1,var2,var3);

I fixed it.
I used this instead.
edit1 = findobj(0, 'tag', 'edit1');
var1 = str2double( get(edit1, 'string') );
edit2 = findobj(0, 'tag', 'edit2');
var2 = str2double( get(edit2, 'string') );
edit3 = findobj(0, 'tag', 'edit3');
var3 = str2double( get(edit3, 'string') );

var1 = str2double( get(handles.edit1, 'string') );
var2 = str2double( get(handles.edit2, 'string') );
var3 = str2double( get(handles.edit3, 'string') );

I still get errors. This is what I get
Dot indexing is not supported for variables of this type.
Error in calculateBerekening>pushbutton1_Callback (line 83) var1 = str2double( get(handles.edit1, 'string') );
Error in gui_mainfcn (line 95) feval(varargin{:});
Error in calculateBerekening (line 42) gui_mainfcn(gui_State, varargin{:});
Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)calculateBerekening('pushbutton1_Callback',hObject,eventdata,guidata(hObject)) Error while evaluating UIControl Callback.

That implies that handles was not a handles structure, which is a problem that would be associated with CreateFcn but not with pushbutton callbacks.
