MATLAB: Conversion of figure window to image window.

image analysisImage Processing Toolbox

I have formed image in a figure window.how do i map this image into image window such that i could trace the co-ordinates of it? And i want to link this image to other program for further process.

There is nothing you have to do. The image is already in an "image window" as you call it. The image is actually in an "axes" control that is sitting on a "figure" window. You're free to start using imfreehand() or whatever you want to trace coordinates. Let me know if you want a demo.

As far as "link this image to other program for further process", I suggest you look at the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F But I'd recommend that you put the axes on the same figure/gui as your other controls (buttons, listboxes, checkboxes, etc.) because it will make it a lot easier.

MATLAB: Create subsets by a moving window.

Anna - assuming that the data from your seismic catalog is in the myData matrix, then you could do the following

fileCount = 1;
for k = 1:length(myData)-50+1
    subsetOfData = myData(k:k+50-1,:);
    % write subsetOfData to file
    filename = sprintf('seismicSubset%03d.txt', fileCount); 
    writematrix(subsetOfData, filename);
    fileCount = fileCount + 1;
end

You'll probably want to come up with a better naming convention for your files (and include where they should be saved to). I haven't tested the above but i think that you get the idea of what can be done.

MATLAB: How to show msbackadj plot within app window.

The msbackadj() function produces a figure when ShowPlot is true or equal to any integer value that specifies a column of input data. There's no way to specify an axes so it will either produce a new figure or it won't produce a plot at all.

I see two ways around this.

The easy way

Use copyobj() to copy the content of the msbackadj() plot on to your app axes and then destroy the external figure.

Pro: It's easy to implement and only requires a few lines of code.

Con: You may see a figure appear and quickly disappear which can be annoying.

See inline comments for details

function BaselineCorrectionTestButtonPushed(app, event)
    % Clear your axes    
    cla(app.UIAxes2) 
    
    % Produce your data and external figure
    ICorr = msbackadj(app.Pixel2,app.I2,'WindowSize',app.window,'StepSize',app.step,'Showplot',true);
    
    % get handle to the axes that were just created in the new figure
    newAx = gca();
    
    % Copy all children of the new axes to your UIAxes
    % This will not copy the legend but you could get the handle to the 
    % legend and apply copyobj() to the legend-handle if you want to copy that, too. 
    % This will also not copy the xlabel and ylabel but that should be easy to 
    % reproduce.
    copyobj(newAx.Children, app.UIAxes2) 
    
    % delete the external figure
    delete(newAx.Parent)
end

The hard way

Open the msbackadj() function and search for the word "figure" (there is only 1 match in the r2019b file). Set a break point at that line and then run your code so that it stops prior to producing the figure. Then step though each line to determine what is being plotted and how those variables were calculated. You can then reproduce those lines of code in your app.

Pro: No external figure needed and it may run a tad faster than the other method (if noticeable at all).

Con: It will take more time to get it to work since there's a lot going on in that function that varies depending on the inputs.
