如何从GUI Matlab中提取数据/图形？

Question

I have this matlab GUI (not made by me of course), and I have been looking everywhere for almost about a week on how I can possibly extract the figures from it to no success. I am at my wits end and was wondering if any one could help?

I want to be able to copy the figure (and save to desktop to extract data from after), or copy the data in a form of a matrix that I can manipulate and save. I thought I'd put the GUI here in case anyone wants to give it a shot and help (I'd be willing to paypal someone cash if they can help me!):

This is how you produce the image:

1. open spec_gui
2. click file, open, select FocusedInfinity.mat
3. press "Calculate"
4. push buttons

   A."XY Profile" & "DimSum" with Elem slider set to "1"

   B."XY Profile" & "DimSum" with Elem slider set to "5"

5. the top window will display an image:

Here's how I'd attack this.

1. Open the figure in GUIDE.

2. That opens the GUIDE editor like so:

3. Right click on the Calculate button and look at the Property Inspector .

4. Then you can look at the properties, look for Callbacks of any type that are defined.

5. Click the Callback worksheet with a pencil icon and it brings up the editor with spec_gui.m and the calcbtn_Callback .

    % --- Executes on button press in calcbtn. function calcbtn_Callback(hObject, eventdata, handles) h=handles.param; h.nu=linspace(h.extfreq(1),h.extfreq(2),h.n_freq); [handles.pList,handles.data]=speccalc('nfile','temp','spec',h.spec, ... 'gamma',h.gamma,'ng',h.n_mode,'nu',h.nu,'np',h.n_r,'silent',1, ... 'dim',1:h.n_dim,'m',h.m','cart',h.cart); handles.file='temp.mat'; handles=update_data(hObject, [], handles); update(hObject, [], handles); 

This is what calculates the figure, you can repeat this process to see what the "XY Profile" & "DimSum" and Elem slider callbacks are and what they do. It'll be a little bit of work, but you'll get it. Otherwise SO is here to help. :-)

Answer 2

OK I DID IT!

With a combo of what MACDUFF and DANGKHOA (thanks so much guys) said and a few hours later!

1. I found out which line in the code the buttons are being utilized (ie what MAC DUFF said)

2. I put a "keyboard" right after, but before the end of the code (ie what DAN KHOA said)

3. When I started the GUI and calculation and pressed the button the matlab script displayed "k"

4. I typed in figure

5. then "imagesc(im)", which "im" was what the GUI was saving the image data as.

BINGO! Thanks guys...so much work sigh
