The idea behind the predictor-corrector methods is to use a suitable combination of an explicit and an implicit technique to obtain a method with better convergence characteristics. The combination of the FE and the AM2 methods is employed often. Here, we use the FE as a predictor equation to get ypn+1and subsequently use

1.13 Predictor-corrector methods The trapezoidal rule differs from the other two that we’ve looked at in that it does not explicitly tell us what the next value of the unknown function is, but instead gives us an equation that must be solved in order to find it.At first sight this seems like a nuisance, but in fact it is a boon,

When considering the numerical solution of ordinary differential equations (ODEs), a predictor–corrector method typically uses an explicit method for the predictor step and an implicit method for the corrector step. Example: Euler method with the trapezoidal rule. A simple predictor–corrector method (known as Heun's method) can be constructed from the Euler method (an explicit method) and the trapezoidal rule (an implicit method). Consider the differential equation ′ = (,), =,

Sep 16, 2019 · Predictor-Corrector Method : The predictor-corrector method is also known as Modified-Euler method. In the Euler method, the tangent is drawn at a point and slope is calculated for a given step size. Thus this method works best with linear functions, but for other cases, there remains a truncation error. To solve this problem the Modified Euler method is introduced.

Use Euler’s method and the trapezium method as a predictor-corrector pair (with one correction at each time step). Take the time step to be h = 0.25 so as to obtain approximations to y(0.25) and y(0.5). Answer Euler’s method, y n+1 = y n + hf n, is the explicit method so we use that to predict. For the first time step we require f 0 = f(0,y
