This video goes through a step-by-step description of the coding of a program to calculate the coordinates of a NACA 4-digit airfoil.
If you would like to know where the equations come from, please see my previous video, located here:

![Explained: How I Set Up MATLAB Scripts [MATLAB]](https://i.ytimg.com/vi/SJ7z7fHpxM8/hqdefault.jpg "Explained: How I Set Up MATLAB Scripts [MATLAB]
In this video I show how I personally set up a MATLAB script before I begin any coding. The title of the code can be more descriptive than the actual name of the file. I like to include who wrote the code. This isnt necessarily important if youre the only one accessing your code, but if you write code in a framework with other people, this helps indicate who actually started the file.
The started and updated dates are important, especially if you have multiple versions of the code (e.g. Code_v1.m and Code_v2.m) because it will help you keep track of changes. I have (dated) notebooks in which I derive the math behind some of my codes, so I can easily compare last update of the code with my notes from that day.
Commenting your code is extremely important! Dont neglect to comment just because you think youll remember what you did. If you write enough code, you WILL forget why you wrote something the way you did, and comments help tremendously.
Code folding and selective execution (using ctrl+enter) can be very convenient when you want to run just a single section of code. I forgot to mention this in the video, but you can also select the code you want to run with your mouse, and then press f9. Im a sucker for code folded sections though.")

This is the third video in my 10-video series on coding a program in MATLAB to compute, display, and save a NACA 4-digit airfoil.
IN THIS VIDEO:
We code the initialization of the code, which governs what happens before the GUI is made visible to the user.

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.
