Probably a stupid question, but i have a test file, which is just a set of commands and instantiation of some classes, but doesn't have any classes. I want to create a function in this file. Is it possible to create a function without having a class.

@Jagdish Ashok: if you are trying to define a function in the middle of a script then this will not works. Scripts and functions cannot be mixed together on one file.

That just sounds like a regular function file to me. For example,
function test_it_out
s = serial('COM5'); %creates an object of class serial
t = vision.VideoReader('rhinos.avi'); %creates an object of class vision.VideoReader

It's the documentation that's a bit "stupid". It doesn't clearly states that the line that declares a (primary/main) function must not be preceded by any executable lines - only by comments.
Your function, testfunc, will work nicely if you put it in a separate file.
See function, Declare function name, inputs, and outputs
