DiffEqBase API Overview

DE types

DiffEqBase.jl defines specialized types and functions for several categories of differential equation problems (ODEs, SDEs, etc.). Most categories have definitions for the following:

Function types (<:AbstractDiffEqFunction), which wrap a Julia function along with additional data such as a mass matrix or additional functions for calculating Jacobians.
Problem types (<:DEProblem), which represent a problem to be solved. They include a function of the corresponding type along with information such as initial conditions, parameter values, and the time span to solve.
Algorithm types (<:DEAlgorithm), which solve DEProblems.
Solution types (<:DESolution), which are the result of an algorithm solving a DEProblem.

See DE Types for documentation of specialized code for each problem type.

Type parameters

The following are common type parameters that appear throughout the package:

uType - Element type of the state vector of a DE function or problem. Typically a subtype of Real.
tType - Type of time variable used in a DE function or problem. Typically a subtype of Real.
isinplace - Boolean value which indicates whether a DE function operates in-place (sets values of an array passed as its first argument rather than returning a new array). Also appears as iip.
