Hi every body. I am using initial guess 1e11 and 0.25 for target parameters 2e11 and 0.33. However, lsqnonlin is not working, and message is as follows:
Initial point is a local minimum.
Optimization completed because the size of the gradient at the initial point
is less than the selected value of the function tolerance.
<stopping criteria details>
Optimization completed: The final point is the initial point.
The first-order optimality measure, 0.000000e+00, is less than
1e-4*options.TolFun = 1.000000e-11.
Optimization Metric Options
relative norm(gradient) = 0.00e+00 1e-4*TolFun = 1e-11 (selected)
