Rectangle

Rectangle

Bases: Term

Basic term that represents the rectangle membership function.

Equation

\(\mu(x) = \begin{cases} h & \mbox{if } s \le x \le e \cr 0 & \mbox{otherwise} \end{cases}\)

where

• \(h\): height of the Term
• \(s\): start of the Rectangle
• \(e\): end of the Rectangle

Attributes

end instance-attribute

end = end

start instance-attribute

start = start

Functions

__init__

__init__(name: str = '', start: float = nan, end: float = nan, height: float = 1.0) -> None
