Detailed Description

template<class T>
class casacore::GNoiseParam< T >

A one dimensional normal distribution.

Intended use:

Internal

Review Status

Test programs:

tFunctionHolder

Prerequisite

• FunctionParam class
• Function class

Etymology

Gaussian Noise generator.

Synopsis

A GNoise is described by a mean and a variance (Note these are not parameters in the Function sense, but more like the order of a polynomial. The defaults are 0 and 1.

Example

GNoiseFunction<Double> sf;
sf();            // = 0.12

Template Type Argument Requirements (T)

• T should have standard numerical operators

Thrown Exceptions

• AipsError if incorrect parameter number specified.
