Hi,
I am interested in what info does extended trace give in NLsolve.jl.
A particular trace reads as
Iter f(x) inf-norm Step 2-norm
------ -------------- --------------
0 1.000000e-01 NaN
* f(x): [0.1, 0.0]
* g(x): [-30.58680355728619 0.0; 0.0 -1.0]
* x: [0.0, 0.0]
* delta: NaN
* rho: NaN
1 2.339203e-02 3.269384e-03
* f(x): [0.02339203027677505, 2.3392030276774175e-7]
* g(x): [-16.27705485965006 0.0; 0.00014309748697635279 -1.0001430974869765]
* x: [0.0032693837985623268, 0.0]
* delta: 1.0
* rho: 0.945281291947572
