Strange error on my source code

Matlab is telling me that my declaration of variables is invalid. I've tried putting a "clear all" before the declaration, but it still tells me there is an error in the code. Does anyone know the answer for this? It seems so trivial...

Can you show ur code to find error in it?

I thought I had attached it, here it is, sorry.

What really need is code and error in context...do whatever it was that caused the error and then cut and paste it here along with whatever function it was source

The part from

   %%diferentes codificacoes

on downwards is not inside any "function". You cannot have a script in the same file you declare a function. You need to move that line through to the end into a different file.

Thanks for the advice. There were other mistakes in the code but only syntax ones. This code was not written by me, it was a friend who helped me with most of it.
