Signature

def rosen_hess_prod(x, p)

Summary

Product of the Hessian matrix of the Rosenbrock function with a vector.

Parameters

x : array_like: 1-D array of points at which the Hessian matrix is to be computed.
p : array_like: 1-D array, the vector to be multiplied by the Hessian matrix.

Returns

rosen_hess_prod : ndarray: The Hessian matrix of the Rosenbrock function at x multiplied by the vector p.

Examples

import numpy as np
from scipy.optimize import rosen_hess_prod
X = 0.1 * np.arange(9)
p = 0.5 * np.arange(9)
rosen_hess_prod(X, p)
