Detailed Description

template<class T>
class casacore::UnaryFunction< T >

A one dimensional unary function

Intended use:

Public interface

Review Status

Test programs:: tFunctionHolder

Prerequisite

Etymology

A 1-dimensional unary hat.

Synopsis

A Unary is described by a height, a center and a width (halfwidth). The value is:

height          (|x-center| <  width)
0.5height          (|x-center| == width)
0               (|x-center| >  width)

The parameters are enumerated by HEIGHT, CENTER and WIDTH. They have default values of (1, 0, 1).

Example

UnaryFunction<Double> sf(5.0, 25.0, 7);

sf(25); // = 5.0

casacore::UnaryFunction::UnaryFunction

UnaryFunction()

Constructs the UnaryFunction, Defaults: height=1, center=0, width=1.

Definition UnaryFunction.h:93

Template Type Argument Requirements (T)

T should have standard numerical operators

Thrown Exceptions
