"Activate" lines with a GUI?

Hi,

i am very new to Matlab so please no blame for "bad" questions.

What I have is a script to do some calculations and display the results afterwards in separate windows. Since i never need all results at the same time, i created a GUI with checkboxes and a "run" button. This way i want to reduce the high calculation time.

My first target is the following:

With the checkboxes i want to determine, which commands / parts of the script are supposed to be run. Triggering the boxes must not activate anything before the "run" button is clicked. Hitting the "run"-Button activates the script like usual, just with less commands.

So instead of

1

2

3

4

5

i want to get something like

1

2

3

checkbox -> 4

checkbox -> 5

checkbox -> 6

To start with i want to be able to switch on/off "figure"-commands.

I hope it is roughly clear what i'm trying to tell.

Thanks

How about an if/else in the pushbotton_Callback function?

Thank you! An if/else in the pushbutton reffering to the results of the if/else's of the checkboxes.

This is easy using nested functions (tested on MATLAB 2012b):

function temp0
%
F = figure();
P = uipanel(...
    'Parent',F,...
    'Units','normalized',...
    'Position',[0.1,0.1,0.7,0.6]);
%
N = 5;
V = 0:N;
H = V;
gap = 0.1;
hgt = (1-(N+1)*gap)/N;
for k = 1:N
    H(k) = uicontrol(...
        'Parent',P,...
        'String',sprintf('Option %d',k),...
        'Style','checkbox',...
        'Units','normalized',...
        'Position',[0.1,gap+(gap+hgt)*(N-k),0.8,hgt]);
end
%
uicontrol(...
    'Parent',F,...
    'String','Run',...
    'Style','pushbutton',...
    'Units','normalized',...
    'Position',[0.1,0.8,0.7,0.1],...
    'Callback',@MyFun);
%
    function MyFun(~,~)
        for n = 1:N
            if get(H(n),'Value')
                fprintf('Option %d has been selected\n',n)
                ... your code here
            end
        end
    end
%
end

And produces this figure with several checkboxes:

And when "run" is clicked it prints this in the command window

>> temp0()
Option 1 has been selected
Option 3 has been selected
Option 4 has been selected
