Input data type for fsolve() for PPL

[teerasak]

@DrD, thank you very much for your help. For the command you provided, it works.

However, if I write the code like this:

Code:


EXPORT temp()
BEGIN
  LOCAL x,y;
  LOCAL equn;
  equn := “[x^2+y-2,x+y^2-2],[x,y],[0,0]”;
  RETURN CAS.fsolve(equn);
END;

It doesn’t work. It just return fsolve(equn). How can we have fsolve() or CAS.fsolve() accept the input from string variable?
