Mathematical.UnaryMinus

UnaryMinus

A component that outputs the negation (additive inverse) of the input signal.

Description

The UnaryMinus block computes the negation of input u. The output y is defined as: y = -u.

Variables

• u(t): Input signal
• y(t): Output signal (negation of u)

Examples

• u = 5 → y = -5
• u = -3.2 → y = 3.2
• u = 0 → y = 0

This component extends from BlockComponents.SISO

Usage

PrimitiveComponents.Mathematical.UnaryMinus()

Connectors

• u - This connector represents a real signal as an input to a component (RealInput)
• y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} y\left( t \right) &= - u\left( t \right) \end{align} \]

# Description
The UnaryMinus block computes the negation of input `u`.
The output `y` is defined as: y = -u.
