Is it possible to use previous time step when I use Clock Block in simulink.

In my model I have to use 2 values of time in every moment of simulation. For example I have time steps returned by Clock Block : [1 2 3 4 5 6 7 8 9 10 ...] and I need to use in my function 2 values: previous and current steps. It looks like MyFunc[0 , 1], MyFunc[1 , 2], MyFunc[2 , 3] until the end of simulation. Is it possible using only Clock Block, or there are some other ways to solve this problem?

Try feeding the clock output through a unit delay block to get the time at the previous simulation step. You should also set your model to use a fixed step solver.
