Increment Real World

Increase real-world value of signal by one

  • Increment Real World block

Libraries:
Simulink / Additional Math & Discrete / Additional Math: Increment - Decrement
HDL Coder / Math Operations

Description

The Increment Real World block increases the real-world value of the signal by one.

Overflows always wrap.

Examples

expand all

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.

Ports

Input

expand all

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

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | fixed point

Output

expand all

Output is the real-world value of the input signal increased by one. Overflows always wrap. The output has the same data type and dimensions as the input.
