Running Octave function - undefined near line 1 column 5

Question

I got a problem with running any Octave function. The function can be as simple as:

function a = testt(k)
  a = k + 5
end

named testt.m and called with commander

a = testt(7)

gives an error: 'testt' undefined near line 1 column 5

I added path before addpath(pwd). I copied some available function from web. And it is still the same. At the same time I'm able to run another function which I wrote two days ago and which is in the same directory:

    function A = fibn_(n)

    B = [0 1];

    for i = 1: n-2

      nkol = size(B,2);
      minus = B(1,nkol);
      minus1 = B(1,nkol-1);

      B(1,nkol+1) = minus1 + minus;

    end;

    A = B;

    end;

I have no idea what is the difference between this two (not only this two but also many other functions that seems to be correct).

Anybody help?

And pwd shoes the folder with the testt.m file, and dir shows the file? — Nick J

It will work fine if you add 'addpath(pwd)' before declaring the function. here is your refined code which worked in my octave 4.2.1

addpath(pwd)
function a = testt(k)
a = k + 5
end
a = testt(7)
