Parameter handling for one dimensional Sinusoid class.

Intended use:

Internal

Review Status

Reviewed By:: UNKNOWN
Date Reviewed:: before2004/08/25
Test programs:: tSinusoid1D

Prerequisite

FunctionParam class
Function1D class

Etymology

A 1-dimensional sinusoid's parameters.

Synopsis

A Sinusoid1D is described by an amplitude, a period, and a location of a peak. The parameters (amplitude, period, and x0) may be changed at run time.

The functional form is A*cos(2*pi(x-x0)/P)

The parameter interface (see FunctionParam class), is used to provide an interface to the Fitting classes.

There are 3 parameters that are used to describe the Sinusoid:

The amplitude of the Sinusoid. This is the value returned using the amplitude member function.
The period of the Sinusoid in the x direction. This is the value returned using the period member function. The period is expressed in full cycles.
The location of a peak of the Sinusoid (i.e. where x=pi+k.2pi)

An enumeration for the AMPLITUDE, PERIOD and X0 parameter index is provided.

This class is in general used implicitly by the Sinusoid1D class only.

Example

Sinusoid1D<Double> sf(5.0, 25.0, 7);
sf(25);            // = -4.911
sf.setAmplitude(1.0);
sf[Sinusoid1D<Double>::PERIOD] = 2.0;                
sf.setX0(0.0);
sf(0.5);             // = 1.0

Template Type Argument Requirements (T)

T should have standard numerical operators and exp() function. Current implementation only tested for real types (and their AutoDiffs).

Thrown Exceptions

Assertion in debug mode if attempt is made to set a negative width
AipsError if incorrect parameter number specified.
