From: fabianpilz Pilz on 6 Jun 2010 01:13 Hallo guys, I have already work with Matlab, but i have one question and i hope one or two guys can help me. Now the question: I like to approximate my measurements, this alresdy work well. Only one point i like to improve, i like that my measurements are the maximums of my approximate function? I hope tha's essantial. Some more explonation, i read my data out of one Excel tool. This data i like for a better analysis to plot my measurements in Matlab. This measurements are six sigma values which i calculat in this excel tool therefore the measurements show at the begining a swinging system which like to reach a constant value. Therefore it was a little bit better if thye approximate function will use the measurements as an max or min value. I hope this small explonation 9s clear enough otherwise i like to show my matlab code, perhaps one person can help my.

I'm sorry, but I am totally clueless as to your goal here. Please be more clear about your problem. John

Hope this helps. Greg
