t=[0:0.01:0.1];
y=[0 7.9060 7.9311 7.9396 7.9425 7.9405 7.9405 7.9405 7.9405 7.9405 7.9405];
The plot came as per expectation ,but after fitting using the estimated value of lambda the curve became quite unusual.Please help me to find the correct fit for the above data set. Actually by fitting the curve i want to find its curvature.

You'll need to show us what you did, and the results. How else do we know that you don't simply have the wrong expectations?
