🗂 File Naming Convention

All code and figure files follow a structured naming convention to clearly indicate the content and source and the structure is explained below:

• fig{n}: Indicates the figure numbers included.

• {paperID}: Refers to the paper from which the figures or simulations are derived:

📌 Example

A file named: fig1x3x5_18_2 means it contains MATLAB code to generate Figures 1, 3, and 5 from the paper coded 18.2.
