Truncated power function : ウィキペディア英語版
Truncated power function
In mathematics, the truncated power function with exponent n is defined as
:x_+^n =
\begin
x^n &:\ x > 0 \\
0 &:\ x \le 0.
\end

In particular,
:x_+ =
\begin
x &:\ x > 0 \\
0 &:\ x \le 0.
\end

and interpret the exponent as conventional power.
==Relations==

* Truncated power functions can be used for construction of B-splines.
* x \mapsto x_+^0 is the Heaviside function.
* \chi_(x) = (b-x)_+^0 - (a-x)_+^0 where \chi is the indicator function.
* Truncated power functions are refinable.
