gpdal_derivative_results()

template<typename T>

auto proxsuite::proxqp::dense::linesearch::gpdal_derivative_results	(	const Model< T > &	qpmodel,
		Results< T > &	qpresults,
		Workspace< T > &	qpwork,
		const Settings< T > &	qpsettings,
		isize	n_constraints,
		T	alpha ) -> PrimalDualDerivativeResult<T>

Stores first derivative and coefficient of the univariate second order polynomial merit function to be canceled by the exact generalized primal-dual linesearch.

Parameters

a	second order polynomial coefficient of the merit function used in the linesearch.
b	first order polynomial coefficient of the merit function used in the linesearch.
grad	derivative of the merit function used in the linesearch.
