const RadiusDependentKernelParameters* IMP::em::KernelParameters::get_params	(	float	radius,
		float	eps = `0.001`
	)

Finds the precomputed parameters given a particle radius.

Parameters:

`[in]`	radius	searching for parameters of this radius
`[in]`	eps	used for numerical stability

Note:: The parameters are indexes by the radius. To maintain numeratical stability, look for a radius within +-eps from the queried radius.
the function return NULL and writes a warning if parameters for this radius were not found.

void IMP::em::KernelParameters::set_params ( float radius )

Sets the parameters that depend on the radius of a given particle.

The other variables of the parameters (rsigsq,timessig,sq2pi3,inv_rsigsq,rnormfac,rkdist) must have been set.

Parameters:

[in] radius the radius
