Re: GUI - reopening previous run

Yes this is the way I have been trying to do it. However I
am not sure how to load the user-defined values (saved from
last run) instead of my default values.

Something likes that-
Check the existence of your user-defined data file,
If yes, load this file, and set values to your control
objects.
Otherwise, set them by default values.

datafile = 'uservals.mat';
if exist(datafile,'file)==2
%% load your data
uservals = load(datafile);%load(datafile) is also OK
name = fieldnames(data);

%% set user-defined value
set(handles.object1, 'Value',getfield(data,name{1}))
....

else
%% set default value
set(handles.object1, 'Value',value1)
...
end



In the uicontrol for the variable I have a box for
"string".
This is the value I have when the GUI opens. How do I
direct
this string to the variable from the workspace/file?

Do you want to get and assign the string in the edit text to
one variable in the workspace???
obj = findobj('parent',gcf,'style','edit');
str = get(obj,'String');

also you could use the functions assignin and evalin.

Hello Anh Huy Phan and thank you for your help.

I am still struggling to implement this. I have been using
SIMULINK so I am only a novice on GUI.

I am now trying to do my task with a more simple GUI. In
mygui.fig I have two variables.

To execute my gui I have directed a pushbutton to a .m file
in the callback uicontrol. so I have a .m file with the lines

_____________________________

%notice that this m-file is NOT a function because
%simulink only allows you to use variables that are within
the main
%workspace
clear all

%make the handles structures available to the main workspace
h =gcf;
handles = guidata(h);

%set the axes to which the data will be plotted to
axes(handles.axes1);

datafile = 'workspace.mat'
if exist(datafile,'file')==2
load(datafile)
end

% get the parameters from the edit text fields
mass=str2num(get(handles.mass,'String'));


%simulate the system
sim('testmodels');

___________________________________

This creates the variable in workspace to pass to SIMULINK.

As you can see I have added your lines of code. However I am
not sure if I should add your other code here or in mygui.m
As you can see I get the parameters from the edit text field
so I just need to set up the if loop correctly. Should I set
it up here or in the mygui.m file. I am not sure of best
practice. Therefore I am not sure how to implement your code
below? Any advice is appreciated.

Thanks


name = fieldnames(data)
set(handles.object1, 'Value',getfield(data,name{1}))
else
set(handles.object1, 'Value',value1)

end
