Sorry, we can't do that. We don't even know what those functions are. Plus it's asking too much from us. It's not like we could convert that program, with it's hundreds of lines of missing code, in a few minutes. It could take hours or more, assuming we could even get the missing functions. I suggest you learn MATLAB and do it yourself, or ask the author if they have it already, or hire someone to do it for you.

And the spacing is a real mess.

I really want ViBe in matlab too. I found this link but i don't have its account to download. if you can, please help downloading. thanks.

Hi Eren,
If you dont have an account to download the files on that page, you can view each file individually, copy the contents to your own *.m file, and run the algorithim then. There are only three files there that you need.

Best bet is to create a psedu code
also check this link if it helps!
vote if found helpful! ;)
