MATLAB: I have 10 text boxes that are used to store data in an column matrix. I cannot save them in a column matrix.

Question

The text boxes will not save them. The first input is recorded, but the moment I input the second value or input, the first element in the matrix becomes zero. What should I do?

Answer 1

Hard to say without code but II suspect that your callbacks look something like

boutput = zeroes(8, 1);

tt = str2double( get(hObject,'string') );

boutput(4) = tt; %for 4th box

save boutput.mat boutput

The problem with this is that it always zeroes the array instead of fetching the current array and storing that.

if isfield(handles, 'boutput')

boutput = handles.boutput;

else

boutput = zeroes(8,1);

end

....

handles.boutput = boutput;

guidata(hObject, handles );
