Detailed Description

Fit engine for analytic single pulse fits.

The concept is that each GSL lmfitter can supply a pair of methods: One that computes a vector of residuals and one that computes a Jacobian matrix of partial derivatives. At the implementation level we have two types of fits we need done: Single pulse fits and double pulse fits (the engines with names ending in 1 or 2). For each fit type we have two fit engines: 1) Serial computation (the engines with names starting with Serial) 2) GPU accelerated (the engines with names starting with Cuda). Finally a fit factory can generate the appropriate fit engine as desired by the actual fit.

Member Function Documentation

jacobian()

void ddastoys::analyticfit::SerialFitEngine1::jacobian ( const gsl_vector *  p, gsl_matrix *  J  )

virtual

Compute the Jacobian matrix.

Parameters

[in]	p	Current fit parameterization.
[out]	J	The Jacobian for this iteration of the fit.

Compute the Jacobian matrix of the fit with respect to current values of the fit parameters. Weights are set to 1.0 and the x, y base class members are the trace data.

Implements ddastoys::CFitEngine.

residuals()

void ddastoys::analyticfit::SerialFitEngine1::residuals ( const gsl_vector *  p, gsl_vector *  r  )

virtual

Compute the vector of residuals.

Parameters

[in]	p	Current fit parameters.
[out]	r	Vector of residual values.

Implements ddastoys::CFitEngine.
