Detailed Description

template<class T>
class casacore::DiracDParam< T >

A one dimensional Dirac delta function.

Intended use:

Internal

Review Status

Test programs:
tFunctionHolder

Prerequisite

Etymology

A 1-dimensional Dirac delta.

Synopsis

A DiracD is described by a height and a center The value is:

height (|x-center| == 0.0)
0 (|x-center| != 0.0)

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

Example

DiracDFunction<Double> sf(5.0, 25.0);
sf(25); // = 5.0
