function

`scipy.optimize._hessian_update_strategy:FullHessianUpdateStrategy.update`

source: build-install/usr/lib/python3.14/site-packages/scipy/optimize/_hessian_update_strategy.py:168

Signature

def update(self, delta_x, delta_grad)

Summary

Update internal matrix.

Extended Summary

Update Hessian matrix or its inverse (depending on how 'approx_type' is defined) using information about the last evaluated points.

Parameters

delta_x : ndarray: The difference between two points the gradient function have been evaluated at: delta_x = x2 - x1.
delta_grad : ndarray: The difference between the gradients: delta_grad = grad(x2) - grad(x1).
