Scalar-Output Function
(Redirected from Real-Valued Function)
A scalar-output function is a numerical-output function whose function range is a real number interval.
- AKA: Real-Valued Output Function.
- Context:
- range: Real Numbers.
- It can range from being a Continuous Real-Valued Function to being a Discontinuous Real-Valued Function.
- It can range from being a Scalar-Output Vector Function, to being a Scalar-Output Tuple Function, to being a Scalar-Output Numeric Function, to being a Scalar-Output Set Function.
- It can range from being a Rational-Valued Function to being an Irrational-Valued Function.
- It can range from being a Scalar-Output Algebraic Function to being a Scalar-Output Function Instance.
- Example(s):
- an Algebraic Function, such as:
- a Linear Function, such as [math]\displaystyle{ f(x) = 2.3 x + 6 }[/math].
- a Polynomial Function, such as [math]\displaystyle{ f(x) = \frac{1}{3} x^2 − 2.3 x + 6 }[/math].
- [math]\displaystyle{ f(\text{Red}) \rightarrow \pi }[/math].
- [math]\displaystyle{ f(1.5) ⇒ 5.1 }[/math].
- [math]\displaystyle{ f(4,Red) \rightarrow \sqrt{2} }[/math].
- [math]\displaystyle{ f(1.1,\text{Red},3.9)\rightarrow 3.0 }[/math].
- a Random Variable Function.
- a Random Scalar Function.
