Undefined Function or Variable - for no reason

For some reason Matlab2013a won't accept any declaration other than predeclared matlab functions. Any custom made function or script I write returns 'Undefined function or variable 'myscriptname'.'

I have the path defined correctly and my function is defined properly. I am simply trying to call functions and scripts located in my working directory.

When it try edit 'myscriptname' - matlab locates and opens the function/scripts for editing, but as soon as I try and run it, matlab gets confused and it wont run.

I have been using matlab for years, never encountered this problem. This has only just occured on a new version I have only just installed today (2013a).

What is weird is that, I can copy those files in a different folder, and sometimes, just sometimes, they will work. For a little while before becoming un-callable again.

Does anyone have any clue what is going on?

Are you using cell mode (%% signs) in those m files? What happens if you type rehash before running any code?

I want to double this. Matlab2013a finds scripts in the current working directory, but other search paths do not work, including the native paths such as e.g. '.../toolbox/matlab/grapics'. 'which' returns "'scriptName' not found" for all extra scripts I put there. It does not depend on cell mode tags (%%) and rehash does not help.

Now interestingly it does not even have an effect if I remove, say, figure.m. The command 'figure' still works, even after calling rehash. At what point does matlab scan all those files in the native search paths?!
