matlab code electromagnetic simulation using FDTD - Dennis Suvillian book

HI Experts

Anybody has matlab codes for this book. Actually in book codes are in c language.

Especially I am interested for chapter-5 patch antenna (Fd3d_patch.c)
If anybody has converted this c code to matlab, can you please share with me

regards

there are various threads discussing this e.g. (https://www.edaboard.com/thread200298.html).
I would be careful though. Sullivan's code is riddled with bugs. So trying to understand how it
is supposed to work and then writing code from scratch may be faster in the long run.
