hello ,
I need help, I'm trying to add my signals in simulink cumulative, I've tried to do it with a delay, with Cum sum in a Matlab function but it doesn't fit, does anyone have an idea and can help.

The Discrete-Time Integrator block can be configured as an accumulator.

For continuous system, feed your signal to an Integrator block.
For discrete system, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.

using a Sum block and a Unit Delay block, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.
