Classes
class	RadialProjection::RadialProjector
	RadialProjector is for projecting a function who has seperatable radial and angular parts: f(r) = f(|r|) * Ylm(theta, phi) onto planewave basis. More...

Namespaces
namespace	RadialProjection

Functions
void	RadialProjection::_mask_func (std::vector< double > &mask)
	get the mask function for SBFFT
void	RadialProjection::_do_mask_on_radial (const int nr1, const double *r, const double *in, const int nr2, const double *mask, double *out)
	do operation w(r)/m(r) on a radial function. The cutoff radius of w(r) is smaller than the cutoff radius of m(r). The m(r) has been rescaled so that r ranges from 0 to 1.
