Hello... i want to save value from "edit" GUI.. I have make it like this http://www.4shared.com/rar/jXNKKYPt/savecontinous.html, but it not suitable with my wish... I want to make value in "data1.mat" is different with "data2.mat" and so on, where the value i got from "edit" GUI when i pressed Save button... Thank you.. :)
function pushbutton1_Callback(hObject, eventdata, handles)
button_state = get(hObject,'Value');
if button_state == get(hObject,'Max')
for k=1:3
% save data to mat-file
x=str2num(get(handles.edit1, 'String'));
y=str2num(get(handles.edit2, 'String'));
z=horzcat(x,y);
myfilename = strcat('data', num2str(k), '.mat');
save (myfilename,'z');
% -------------
% this code to check value of data1.mat and so on
nil1 = isequal(strcat('data', num2str(k), '.mat'), strcat('data', num2str(k+1), '.mat'));
% in this chapter, i hope value of data2.mat and so on have save
% different value,, but it's not work.. How to save them with different
% value..??
if nil1 == 1
for k = 2:3
x=str2num(get(handles.edit1, 'String'));
y=str2num(get(handles.edit2, 'String'));
z=horzcat(x,y);
myfilename = strcat('data', num2str(k+1), '.mat');
save (myfilename,'z');
end
else
% when the button pressed, the "edittext" will be empty. So, user
% can input the value again
set(handles.edit1,'String','')
set(handles.edit2,'String','')
end
% ---------------------
end
else if button_state == get(hObject,'Min')
end
end

A loop over k nested inside another loop over k is never a good idea.

Not exactly sure what you're trying to do, but nil1 will always be false since k is never equal to k+1. So your function will clear the edit fields (edit1 and edit2) on the first iteration, and in fact every iteration. The nil1 == 1 code will never get executed.

Not sure how x went from 5 to 7 and y went from 2 to 4, but see the code I posted and try to adapt it to whatever you want/need.

Try this (untested):
function pushbutton1_Callback(hObject, eventdata, handles)
folder = pwd; % or wherever you want.
try
% save data to mat-file
x=str2double(get(handles.edit1, 'String'));
y=str2double(get(handles.edit2, 'String'));
z = [x y];
for k = 1 : 3
% Save the file.
baseFileName = sprintf('data %d.mat', k);
fullFileName = fullfile(folder, baseFileName);
save (fullFileName,'z');
% Now we prepare for next time.
% Note: not really sure how x and y are
% supposed to be different each time through the loop.
x=str2num(get(handles.edit1, 'String'));
y=str2num(get(handles.edit2, 'String'));
z = [x y];
% Clear edit 2 for some reason.
set(handles.edit2,'String','')
end
% ---------------------
catch ME
errorMessage = sprintf('Error in function pushbutton1_Callback():\n%s', ME.message);
uiwait(warndlg(errorMessage));
end
