How to hold a value in simulink ?

Hello,

I search how to hold a value in my simulink model for an operation : I need to keep the latest value of my model and then add it to my signal until the input signal get to 0 again. It is like a vertical translation of my signal by the latest value calculated in the latest period.

Something like that :

Can a block in simulink do that or hold the latest value to add it to all the next iteration ?

Here is my simulink model :

K has the value 12.

A1 has the value 9.5e-5.

In input I have a custom repeating sequence from the fonction in the m file (force.m) :

I'm sorry for the size of each screen capture, I don't know how to manage it.

Thank you for your time.

In Simulink, you can hold the latest value of a signal until a reset condition (like the signal crossing zero) by using a zero-crossing or change-detection block to trigger a subsystem that stores the value in a Memory or Unit Delay block; this stored value is then continuously added to the live signal through an Add block, effectively applying a vertical shift that updates only at each trigger event, keeping the offset constant between events until the input hits zero again.
