Decrement Time To Zero
R2026bDecrease real-world value of signal by sample time, but only to zero
Decrement Time To Zero block
To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.
Libraries:

Additional Math: Increment - Decrement
Description
The Decrement Time To Zero block decreases the real-world value of the
signal by the sample time, Ts. The output never goes below
zero.
Examples
This example shows how to increase and decrease the real-world value of a signal using the following blocks:
Increment Real World
Decrement Real World
Decrement Time To Zero
Decrement To Zero
The Scope block shows the output of a Sine Wave block with amplitude 5, as well as the real-world value of that signal incremented and decremented by one.
The Scope1 block shows the output of a Sine Wave block with amplitude 3, as well as the output of the Decrement To Zero and Decrement Time To Zero blocks:
The Decrement To Zero block decreases the input sine wave signal by one, and ensures the value never goes below zero.
The Decrement Time To Zero block decreases the input sine wave signal by the sample time,
Ts, and ensures that the value never goes below zero.
Limitations
The Decrement Time To Zero block works only with fixed sample rates and does not work inside a triggered subsystem.
