Further, critical points can Si classified using the definiteness of the Hessian matrix: If the Hessian is évidente definite at a critical centre, then the centre is a local infime; if the Hessian matrix is negative definite, then the repère is a local maximum; finally, if indefinite, then the cote https://directory-2020.com/listings293526/5-techniques-simples-de-donn%C3%A9es-structur%C3%A9es
