Parameters:

vnumpy.ndarray, shape (n,)

Direction along which the curvature of the quadratic models of the nonlinear equality functions is evaluated.

masknumpy.ndarray, shape (m_nonlinear_eq,), optional

Mask of the quadratic models to consider.

Returns:

numpy.ndarray

Curvature of the quadratic models of the nonlinear equality functions along v.
