I do not know if you can do the following in Simulink. But can you force the simulation of a model according to particular steps?

I want the simulation model solutions at specific steps. These steps have defined as the vector, the size of the steps is variable.

Thank you very much, the solution is perfect as you say. I have tried to define the vector steps in the workspace as "step" and then call it from _ Ouput times_ as [step], so that I do not have to enter the values manually in Output times but it does not work. It is a pity. But, again, your solution is perfect.
