Description
Piecewise, smooth function that increases linearly with negative arguments.
f(x) = ≤ft\{
\begin{array}{ll}
-(x - x_0/2) & x < 0 \\
\frac{1}{2x_0}(x - x_0)^2 & 0 < x <x_0 \\
0 & x ≥ x_0
\end{array} \right.
Usage
1
f(x, x0)
Arguments
x
Main argument
x0
The cut-off parameter. Above this value the function is zero.
