probnum.problems.zoo.quad.hennig2d(c=None)[source]

The two-dimensional hennig function integrated wrt the Lebesgue measure. 1

The integrand is

\[f(x) = e^{-x^{\intercal}c x -\sin(3\|x\|^2)}\]

on the domain \(\Omega=[-3, 3]^2\). Above, \(c\) is the c parameter.

Parameters

c (Optional[ndarray]) – A positive definite matrix of shape (2, 2). Defaults to [[1, .5], [.5, 1]].

Returns

The quadrature problem.

Return type

quad_problem
