# Dear All, I am new to MATLAb GUI and want to create one. My program should work in the following sequence. 1) Select option of polarity from a pop-up menu (total two options are available) 2) load file according to polarity selected 3) execute part

My Matlab script is as follows (which works perfectly but i have to change it to GUI for user readiness)

Hello Sumera,
If you've already got the code, the hard part is done :) To start with the GUI, I'll recommend using guide().
From matlab command window, run
guide
which will open a window. Select the "Create new GUI' tab, the select "Blank GUI", then "OK" button. This will open an untitled figure where you can drag and drop GUI components and design your GUI. Hover your mouse over the GUI components on the left to see what they are. You'll see pop-up Menu and others. Once you drag them to the figure space, right click on the component and open "property inspector". Here you'll have all of the options available for that component. You can search for answers on google or within this forum to learn about those options.
When you save the figure it will produce code with callback functions etc. If you get stuck, feel free to ask follow-up questions.

Question copied here: Hi, but how would i link the result of my code in .m file (lsqr(R_pp, Vf_pp) in my original code) to the GUI?
You have to use the handle to the object. In my code above, 'edit1' is the handle to the object. If you're using GUIDE, use the 'handles' structure.
handles.edit1.String = 'blah';

Thank you very much for the clarification.
