Decrement To Zero

Decrease real-world value of signal by one, but only to zero

• Library:

• Simulink / Additional Math & Discrete / Additional Math: Increment - Decrement

Description

The Decrement To Zero block decreases the real-world value of the signal by one. The output never goes below zero.

Ports

Input

Port_1 — Input signal

scalar | vector | matrix

Input signal, specified as a scalar, vector, or matrix.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | fixed point

Output

Port_1 — Output signal

scalar | vector | matrix

Output is the real-world value of the input signal decreased by one. The output never goes below zero. The output has the same data type and dimensions as the input.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | fixed point

Model Examples

Increment and Decrement Real-World Values

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using Simulink® Coder™.

The code generator does not explicitly group primitive blocks that constitute a nonatomic masked subsystem block in the generated code. This flexibility allows for more efficient code generation. In certain cases, you can achieve grouping by configuring the masked subsystem block to execute as an atomic unit by selecting the Treat as atomic unit option.

Fixed-Point Conversion
Convert floating-point algorithms to fixed point using Fixed-Point Designer™.
