Constant Vector as Argument in PPL

I think you are on the right track. It appears that normalize() is a command dedicated to CAS, and passing a parameter inside a PPL program might not be handled correctly. Therefore, when you enter the program not as pure PPL, but as a CAS region, everything works correctly:

Code:

#cas
bla:=
normalize([0,0,-1]);
#end

However, a simpler solution is to substitute individual elements of the vector one by one, e.g., normalize[0,0,-1] instead of normalize([0,0,-1]).
Then your program will look like this:

Code:

export bla()
begin
  return normalize(0,0,-1);
end;

This should solve your problem.
