How to fit an ellipse
in [Matlab]

From: Madhu Shurpali on 21 Apr 2010 09:33 Hello Everybody, I have test data of Force Vs Displacement. When I plot Disp Vs Force, I can see that its very close to ellipse. How can I fit an ellipse to this data ? I mean the plot is very close to the equation: (Disp^2/a^2) +(force^2/b^2)=1; How do I estimate a and b .. Thanks Madhu
