I'm writing a GUI where i count seven values and put on a uitable. I want to push a button and, when i have new results, I want to append them down from the older several times. The idea is that when i push the button Save Results to Text File these values go to a text file named "My Results.txt" and when I have new values to append them down from these. Something like this

hammer -0.148 -0.2706 e.t.c pliers -0.248 -0.8979 e.t.c

My values go to the table with a separate button. The code is:

data = get(handles.uitable2, 'data');
data = {(get(handles.name,'String')),handles.imload1,handles.imload2,handles.imload3,handles.imload4,handles.imload5,handles.imload6,handles.imload7};
set(handles.uitable2, 'data', data);

Any help?

在 MATLAB Online 中打开

You get data from the uitable, but then you just overwrite it with your new data. You need to assign the new data to another variable and then append

data = get(handles.uitable2, 'data');
newData = {(get(handles.name,'String')),handles.imload1,handles.imload2,handles.imload3,handles.imload4,handles.imload5,handles.imload6,handles.imload7};
set(handles.uitable2, 'data', data);
data = [data; newData];
set(handles.uitable2, 'data'); % or handles.uitable2.Data = data;
