Good afternoon. My problem is as follows. I have 2 guide, one depends on another. What happens is that the guide number 1 has certain data that I need to transfer for the creation of the guide 2, in which there will be a table (of 2 columns) that should be created automatically with the data of the guide one and that will have "n" number of rows I already managed to get the table in guide 2 to be created as I need it, however I can not get the data that I enter (by keyboard) to keep on the table. I leave the cogigos if someone can tell me what is happening:

Thank you very much and I am attentive to your answers.

for the guide 1:

 handles.data_form2_will_need = KC;
 guidata(hObject,handles);
 form2_h = form2();
 %-------------------

for the guide 2:

function CalcularDin_Callback(hObject, eventdata, handles)
% hObject    handle to CalcularDin (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
syms w
global NP
for k=1:NP 
    
  Mat_masa = get(handles.TablaMasa,'Data');
  
end 

function form2_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 form2 (see VARARGIN)
% Choose default command line output for form2
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
%-------------------------------------------------------
global NP
handles.form1_h = findobj(groot, 'tag', 'form1');
handles1 = guidata(handles.form1_h);      %this is form1's handles
handles.data_form2_needs = handles1.data_form2_will_need;
guidata(hObject, handles)
TTT=handles.data_form2_needs;
guidata(hObject, handles)
NumPiso=  length (   TTT ( : , 1 )    ) - 1             ;
num_elem=cell(NumPiso,2);
num_elem(:,:)={''};
set(handles.TablaMasa,'Data',num_elem);
NP=NumPiso;
for k=1:2      %-length(NP) %- 
    
 NND(k,1) = NumPiso; 
 NumPiso=NumPiso-1; 
 set(handles.TablaMasa,'Data', NND);
 
end%-

I do not have more code in the Guide 2. It's everything I have programmed.

I would suggest using uitable and storing it in a handle. You can save or export the handle from one gui to the next. Then it's just a matter of transferring the data. I found using uitable very useful when updating a plot in real time.

Have you considered using appdata instead of guidata?

In this matlab answer (Appdata answer with link), there is a link to a great video by Doug Hull (former Mathworks employee) that addresses your situation directly and shows how to use appdata.
