predictor-corrector methods predictor-corrector methods[′pri¦dik·tər kə′rek·tər ‚meth·ədz] (mathematics) Methods of calculating numerical solutions of differential equations that employ two formulas, the first of which predicts the value of the solution function at a point x in terms of the values and derivatives of the function at previous points where these have already been calculated, enabling approximations to the derivatives at x to be obtained, while the second corrects the value of the function at x by using the newly calculated values. |
