jacobian()

virtual Tensor<double> madness::SolverTargetInterface::jacobian ( const Tensor< double > &  x )

inlinevirtual

Some solvers require the jacobian or are faster if an analytic form is available.

J(i,j) = partial F[i] over partial x[j] where F(x) is the vector valued residual

provides_jacobian()

virtual bool madness::SolverTargetInterface::provides_jacobian ( ) const

inlinevirtual

Override this to return true if the Jacobian is implemented.

residual()

virtual Tensor<double> madness::SolverTargetInterface::residual ( const Tensor< double > &  x )

pure virtual

Should return the resdiual (vector F(x))

residual_and_jacobian()

virtual void madness::SolverTargetInterface::residual_and_jacobian ( const Tensor< double > &  x, Tensor< double > &  residual, Tensor< double > &  jacobian  )

inlinevirtual

Implement this if advantageous to compute residual and jacobian simultaneously.
