Models.ceq(x, mask=None)[source]#

Evaluate the quadratic models of the nonlinear equality functions at a given point.

Parameters:

xnumpy.ndarray, shape (n,): Point at which to evaluate the quadratic models of the nonlinear equality functions.
masknumpy.ndarray, shape (m_nonlinear_eq,), optional: Mask of the quadratic models to consider.

Returns:

numpy.ndarray: Values of the quadratic model of the nonlinear equality functions.
