`scipy.optimize._lsq.dogbox:dogleg_step`

source: build-install/usr/lib/python3.14/site-packages/scipy/optimize/_lsq/dogbox.py:108

Signature

def dogleg_step(x, newton_step, g, a, b, tr_bounds, lb, ub)

Summary

Find dogleg step in a rectangular region.

Returns

step : ndarray, shape (n,): Computed dogleg step.
bound_hits : ndarray of int, shape (n,): Each component shows whether a corresponding variable hits the initial bound after the step is taken: * 0 - a variable doesn't hit the bound. * -1 - lower bound is hit. * 1 - upper bound is hit.
tr_hit : bool: Whether the step hit the boundary of the trust-region.
