Member Function Documentation

eval()

double eval

(

double

x

)

const

Evaluate the current density Gaussian model at the specified point.

Returns the intensities (i.e. probabilities scaled by the factor 'A') of the PDF at the given positions. This function can be called with any set of parameters, e.g. the initial parameters (to get a 'before-fit' status), or after fitting.

log_eval_no_normalize()

double log_eval_no_normalize

(

double

x

)

const

Evaluate the current log density of the Gaussian model at the specified point.

Returns the intensities (i.e. probabilities scaled by the factor 'A') of the PDF at the given positions. This function can be called with any set of parameters, e.g. the initial parameters (to get a 'before-fit' status), or after fitting.
