Method Detail

shovel

private static final VectorG[] shovel(VectorG t)

Converts a VectorG into a Vector1D[]

setPeriod

public void setPeriod(double p)

Sets the period.

getParameterCount

public int getParameterCount()

Return 3.

Returns:

The number of parameters in the model. This equals the dimension of the input vector in DataModel.getModel(vec_math.VectorG).

getModel

public double[] getModel(VectorG amp)

We convert the model vector into a.0+a.1*cos(2pi/P*(t-a.2))

Specified by:

getModel in interface DataModel

Overrides:

getModel in class AbstractDataModel

Parameters:

amp - The model parameters

Returns:

A model for the data points depending on the model parameters.

evaluateModel

public double evaluateModel(VectorG amp,
                            VectorG t)

We convert the model vector into a.0+a.1*cos(2pi/P*(t.0-a.2))

Parameters:

amp - The model parameters

t - The (one)dimensional vector of independant variables.
