A computational tool designed to approximate solutions to ordinary differential equations using a family of numerical algorithms. It automates the repetitive calculations involved in these methods, providing numerical solutions at discrete points within a specified interval. For instance, when modeling population growth described by a differential equation, this automates the process of estimating the population size at different time points.
The utility of such a device lies in its ability to handle complex or nonlinear differential equations that lack analytical solutions. It saves time and reduces the potential for human error, particularly in fields such as engineering, physics, and economics, where such equations frequently arise. These algorithms have a rich history, developed by mathematicians Carl Runge and Martin Kutta, offering varying orders of accuracy for the approximations.
