Because these are plain-text M-files, they are easily shared, version-controlled (e.g., with Git), and adapted. A heat-transfer code can be converted to a mass-transport code simply by renaming variables and changing the physical interpretation of the element matrix—a task that takes minutes, not weeks. This reusability is why repositories like GitHub and MATLAB File Exchange are flooded with "hot" FEA toolboxes. % Vectorized assembly blueprint I = zeros(num_elem *
