function

`scipy.optimize._hessian_update_strategy:HessianUpdateStrategy.initialize`

source: build-install/usr/lib/python3.14/site-packages/scipy/optimize/_hessian_update_strategy.py:37

Signature

def initialize(self, n, approx_type)

Summary

Initialize internal matrix.

Extended Summary

Allocate internal memory for storing and updating the Hessian or its inverse.

Parameters

n : int: Problem dimension.
approx_type : {'hess', 'inv_hess'}: Selects either the Hessian or the inverse Hessian. When set to 'hess' the Hessian will be stored and updated. When set to 'inv_hess' its inverse will be used instead.
