Hi Everyone, I am wondering what is the correct way to do subtraction of consecutive values of an array in Simulink? For example, if an output of a block is [1,2,3,4,...] and I need to calculate [1,2-1,3-2,4-3,...]. Knowing, both vectors are needed to execute the Simulink scheme. what is the best way to do that? please help
Thanks in advance,

You can use a time delay block and use fixed step solver. Set the time delay to be exactly the time step used by the solver. You connect the signal to the time delay block. Then to get the vector you want, you subtract output of time delay block from the original signal.

Thank you Aquatris for your help. Are you referring to the Unit Delay block? would the Memory block be also another option for this case? thanks again,

I was thinking of transport delay block but you can also use unit delay block as well. I do not know much about the memory block.
