Ode solver libraries

Definition

ODE solver libraries are software collections designed to numerically solve ordinary differential equations (ODEs) using various algorithms and methods. These libraries provide users with pre-built functions and tools that simplify the process of solving ODEs, making it easier to handle complex problems in science and engineering. They often include implementations of higher-order methods, such as Taylor methods, which can yield more accurate solutions with fewer computational resources.
