Specify the size of the first time step that the solver takes.
Category: Solver
Default:
auto
By default, the solver selects an initial step size by examining the derivatives of the states at the start time.
Be careful when increasing the initial step size. If the first step size is too large, the solver might step over important behavior.
The initial step size parameter is a suggested first step size. The solver tries this step size but reduces it if error criteria are not satisfied.
This parameter is enabled only if the solver Type is set to Variable-step.
