ode object workflow tutorial

Define and solve ODE problems with class objects.

📄Description

The ode class stores a problem definition, including the equation, initial state, parameters, events, mass matrix, Jacobian, and solver options.

Property	Purpose
ODEFcn, InitialValue	Define the differential equation and initial state.
Solver, SolverOptions	Select the integration method and its options.
EventDefinition, MassMatrix, Jacobian	Add zero crossing, mass matrix, or Jacobian information.
Sensitivity, DelayDefinition	Add sensitivities or delayed states when supported by the selected workflow.

Call solve to obtain a result object, or solutionFcn to obtain an interpolation function together with the result object.

💡Examples

Create a reusable problem object.

problem = ode('ODEFcn', @(t,y,rate) -rate * y, ...
  'InitialValue', 1, 'Parameters', {2});
result = solve(problem, 0, 1)

Use solutionFcn for interpolation.

problem = ode('ODEFcn', @(t,y) -y, 'InitialValue', 1);
[f, result] = solutionFcn(problem, 0, 1);
f(0.5)
