| const double function::heavyside | ( | const double | x ) | [inline] |
The heavyside step-function 
, also known as the unit stpe-function, is defined as:
![\[ H(x)=\left\{\begin{array}{cc}0&x<0\\1&x\geq0\end{array}\right.\quad. \]](form_15.png)
| const double function::sigmoid | ( | const double | x ) | [inline] |
A process that exhibits a progression from small-to-large and accelerates can sometimes be mapped using a Sigmoid function. This is particuarily useful when a detailed description of the process is lacking. The Sigmoid function 
is defined as:
![\[ S(x)=\frac{1}{1+e^{-x}}\quad. \]](form_17.png)
