The source/vortex panel method code in this video is a combination of the source and vortex panel methods that I have used in my previous videos. This code solves some of the problems that were mentioned in my "Vortex Panel Method: Airfoil" video.
In this penultimate video of my Panel Methods series, we will look at how to populate the matrix system to obtain the solution of the source and vortex strengths. Then we'll go through a bunch of examples of different airfoils to see how well this method works. Comparisons of the lift coefficient, moment coefficient, and pressure coefficient to XFOIL will be made.
In the next (and last) video of this series, we will update this code to be able to work with any number of airfoils.

===== NOTES =====
→ The code is also available in Python, but I didn't include it in this video.
→ The streamline computation section in the Python code takes a really long time to run in comparison to the same MATLAB code. I'm assuming it has to do with the external function calls taking longer, but if you have any suggestions on speeding up that aspect of the code, please let me know.

![Explained: Popup Menu GUI [MATLAB]](https://i.ytimg.com/vi/Wv6aSJ6ifaQ/mqdefault.jpg "Explained: Popup Menu GUI [MATLAB]
Pop-up menus can be used to make a selection from a list of items. This video shows how to get the users input from a pop-up menu in a MATLAB GUI.
Tip:
The method described in the video gives you a little bit more information to work with when extracting data from the popup menu, but if you want the most efficient code, you can use the code below.
popVal = get(hObject,Value);
assignin(base,popVal,popVal);
In this code, youre simply getting the selected value. The first choice is 1, the second choice is 2, and so on. You can then immediately assign this variable back into the base workspace. This code is much simpler, but you also wont have a variable with the strings of all the choices available. In most of my applications, I dont care about the actual strings, just about the value thats selected.")
