- Store the data inside the GUI instead of the root object, where they are shared with all other applications, which write to the root object. This has the same drawbacks as using global variables.
- Do not rely on the current folder. A user can change the current folder, or a callback of the GUI. So add a specific folder to the file, e.g.

I am testing the number of data file in my GUI, Now I want to store the output data of each file . My question is how can i incrementally save the output on a list.
Kp = getappdata(0,'Kp')
Kr = getappdata(0,'Kr')
if exist('myData.mat','file')
S=load('myData.mat');
gain=S.gain;
else
gain = struct('Kp','Kr');
gain.Kp = Kp;
gain.Kr = Kr;
end
save('myData.mat','gain');
it just stores the first data,,,please help

Kp = getappdata(0, 'Kp');
Kr = getappdata(0, 'Kr');
if isfile('myData.mat') % older: exist('myData.mat','file')
S = load('myData.mat');
gain = S.gain;
gain.Kp(end + 1) = Kp;
gain.Kr(end + 1) = Kr;
else
gain.Kp = Kp;
gain.Kr = Kr;
end
save('myData.mat', 'gain');
Hints:
myPath = fileparts(mfilename('fullpath'));
file = fullfile(myPath, 'myDFata.mat');
if isfile(file)
S = load(file);
... etc.
end
Using absolute path names is safer.
