Also known as preconditioning
In mathematics, preconditioning is the application of a transformation, called the preconditioner, that conditions a given problem into a form that is more suitable for numerical solving methods. Preconditioning is typically related to reducing a condition number of the problem. The preconditioned problem is then usually solved by an iterative method.
En algèbre linéaire et en analyse numérique, un préconditionneur d'une matrice est une matrice telle que le conditionnement de est plus petit que celui de .
