toc vector in GUI Matlab

Question

I have created a GUI, using GUIDE. I have added pushbuttons which perform a task. The start button, plots a graph and plays a wavefile that I have assigned to it. in the start button I have added as well a 'tic'.

on the other side of the GUI is have another button, the save button. The function of that button is to save to a vector the exact time that I push the button. The code that I have used saves only the last instance, while I want to be able to see all of the elements of that vector.

  handles.counter.push(handles.count + 1)
  handles.sfront(size(handles.counter)) = toc

Is there a way to save all of the instances to the sfront vector?

Thank you in advance!

Answer 1

You have to store your handles every time before the end of callback function.

Use GUIDATA:

guidata(hObject,handles)

Answer 2

To add a new element to the end of a vector use:

handles.sfront(end+1) = toc;

Then call guidata(hObject,handles) to store the updated version of handles.

I can't recreate your entire GUI here, but here's an example of storing multiple toc outputs in a vector. Takes about 10 seconds to run:

tic
tocList = [];
for i = 1:5
    tocList(end+1) = toc;
    pause(2)
end
