Getting the scope to show sum of time series output with respect to time

2 views (last 30 days)
I have a value that changes with respect to time due to arithmetic function. Instead of viewing the new output with respect to time, I would like to see the new output + sum of previous outputs with respect to time.
Please help me with this. I need to learn how to do this in simulink or if there is a block/function that I can use?

James, you could use the Cumulative Sum block. It is included in the DSP System Toolbox.

I have a similar problem. Mischa, can you please explain how I can implement such a mechanism so I will get the sum of all the values? It's a value that changes with respect to time: a sum of all the energie used by a radiator in a week.
regards, Brent
