Method Detail

getNbEstimatedParameters

int getNbEstimatedParameters()

Get the number of estimated parameters.

Returns:

number of estimated parameters

getEstimatedParameters

void getEstimatedParameters(double[] parameters,
                          int start,
                          int length)
                            throws RuggedException

Get the current values of the estimated parameters.

Parameters:

parameters - global array where to put the parameters

start - start index of the array slice to consider

length - number of elements in the array slice to consider

Throws:

RuggedException - if the size of the slice does not match the number of estimated parameters

setEstimatedParameters

void setEstimatedParameters(double[] parameters,
                          int start,
                          int length)
                            throws RuggedException

Set new values for the estimated parameters.

Parameters:

parameters - global array containing the parameters to set (among others)

start - start index of the array slice to consider

length - number of elements in the array slice to consider

Throws:

RuggedException - if the size of the slice does not match the number of estimated parameters
