It's a bit hard to say as you don't show the code in your question, but it may be that you have not assigned a value to the output argument "y" (and maybe others) in your function thestest.

That is, if your function starts

function y = thestest(...)

there should be a line in it somewhere that looks like

y = ... ;

You should perhaps also look at the structure of the m-file. Does it contain more than one function definition?

yaa there is an other function in my code

[David Young]

OK, I guess it is just that you need some assignment to y.
