Thanks a lot I Like Serena for your kind welcome and reply to my question :)
Y and M are two different physical values. One is height change (I am tracking the height) and the other is mass. I start collecting each of these two data sets from time zero to t(final). Would that still be possible...
I have been looking how to use the Levenberg Marqurdt algorithm for minimizing the errors of two functions at the same time. I looked up this topic in the internet and the only useful thing I found was a thread between "I like Serena" and "thomas430" in summer 2011...
