I would like to know why the file:

  # hyp.m

  function r=hyp(x,y)

  # hypoténuse d'un triangle de côtés x et y

  r=sqrt(x*x+y*y)

  endfunction

 "

always alert :

    " 

   >> hyp

   error: 'x' undefined near line 4 column 8

   error: called from

    hyp at line 4 column 2

   error: evaluating argument list element number 1

   error: called from

    hyp at line 4 column 2

 "

Fortunately, this is not a crashing error.

That problem happens with all my files.

I do not know to declare in function-arguments a variable, 

 for instance x as real, y as integer, m as scalar.

 

After you made the file hyp.m, you must use it this way:

hyp(3,4)

 

 

I also would like to change at the screen the shape of result 

 from a  "for i=1:30,disp(i^2),endfor"  in order to 

 request in a list-shape rather that column-shape, 

Try

i=1:30;

i.^2

 

 (with "disp" or another command).
