Or the numeric approximation to it may have an imaginary component at some points (ie, not a real number), or you could be dividing by zero at some point and getting undefined values. Without more information it's hard to tell what's wrong. > How can I get this plots? Can I ignore these error messages? > You cannot ignore the problems. If it's simply a problem of a small imaginary component that you know is the result of floating point error and is not mathematically significant then simply use Re. Ssezi
