Simulink: Default Integration Time

Hi,

If I fix sample time of some 'to workspace' block, it changes its integration time for 'integrator' block (continuous library) ?

What's simulink default integration time (of ODE45) ?

Thanks

I am assuming you meant to say "sample time" and not "integration time". Please see Viewing Sample Time Display for information on how you can find out the sample-time of your block.

ode45 is not fixed-time integration method - it has variable sample time. You can choose fixed time integration method from Simulation/Configuration Parameters To check sample time you can use a tip described by Kaustubha Govind
