Re: [sligthly OT] phantom line error

[Shai Ayal]

You should call the function from the octave command line like this:
[EX, A, r] = E_X(R);

now you should be able to see EX , A and R

note that the return value was changed to EX so that it won't clash with
the E_X functions name.

If this helped you than I really recommend you do some introductory
reading on the matlab language so that you understand basic concpts like
scripts, functions, local variables etc. I have no recommendation for such
material, but I'm sure googling will turn something up
