This is the last of the elementary flow videos, and here we will combine uniform flow with vortex flow. After showing the Cartesian velocity components on the board, we will go through a script to compute the combined flow-field and calculate the circulation around some arbitrary curves.

In this video, we go through the X and Y velocity expression geometric integrals for the vortex panel method. This is the last geometric integral derivation we will need.

![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.")
