# matlab.ode.options.IDAS Properties

`matlab.ode.options.IDAS`

objects are used with `ode`

objects to
specify options for the solution of ordinary differential equations. `ode`

objects automatically populate the `SolverOptions`

property with an options object specific to the selected
solver, so you generally do not need to create `matlab.ode.options.IDAS`

objects
explicitly.

Specify options for the ODE problem by changing property values of the
`matlab.ode.options.IDAS`

object using dot notation. For example, if
`F`

is an `ode`

object, then
`F.SolverOptions.InitialStep = 1e-3`

specifies an initial step size for
the solver to take.
