void IMP::saxs::DerivativeCalculator::compute_chisquare_derivative ( const Profile model_profile,
const Particles particles1,
const Particles particles2,
Vector< algebra::Vector3D > &  derivatives,
const Vector< double > &  effect_size 
) const

compute derivatives for particles1 with respect to particles2

This method is needed for rigid bodies when particles1 and particles2 are particles of two rigid bodies. In this case the particles of the same rigid body are ignored.

Parameters
[in]model_profileThe current profile of particles
[in]particles1Derivative will be computed for each particle
[in]particles2Derivative will be computed relative to this set
[in]derivativesOutput vector
[in]effect_sizeEffect size
void IMP::saxs::DerivativeCalculator::compute_chisquare_derivative ( const Profile model_profile,
const Particles particles,
Vector< algebra::Vector3D > &  derivatives,
const Vector< double > &  effect_size 
) const

compute derivatives for particles

Parameters
[in]model_profileThe current profile of particles
[in]particlesDerivative will be computed for each particle
[in]derivativesOutput vector
[in]effect_sizeEffect size
