Detailed Description
template<class T>
class casacore::KaiserBFunction< T >
A one dimensional Kaiser-Bessel function
Intended use:
Public interface
Review Status
- Test programs:
- tFunctionHolder
Prerequisite
Etymology
A Kaiser-Bessel function
Synopsis
A Kaiser-Bessel is described by a height, a center, a width (halfwidth) and a parameter. The parameters are enumerated by HEIGHT, CENTER, WIDTH, KBPAR. They have default values of (1, 0, 1, 2.5).
Example
KaiserBFunction<Double> sf;
sf(0); // = 1.0
Template Type Argument Requirements (T)
- T should have standard numerical operators
Thrown Exceptions
- AipsError if incorrect parameter number specified.
