delete zero in signal

My current signal is shown in the figure, which can be seen as continuous steps. I want to obtain the vertices of these peaks and then connect them one by one to form a discount, becoming a new signal that can be input into other modules of Simulink. How to achieve this

Your question is a bit ambigious but if you just want to remove the 0 s from the signal you can use a switch and delay block to ignore 0 values.
