Oh, and Matlab warns about > the polynomial being badly conditioned. > Hmm, I'm inclined to say a norm of 0.4 is much better than a norm of 6.3, rather than only slight better. But anyway, the renormalisation approach I outlined here results in an octave norm of 0.082, which is certainly much better than 6.3. The renormalisation keeps the polynomial from being badly conditioned. Drew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
