Namespaces
namespace	syten
	Syten namespace.

namespace	syten::k_to_y
	Functions which, when given a momentum on the ring k, give the coordinate y at which we want to place this momentum.

Macros
#define	SYTEN_KTOY_DEFAULT_MAP "linear"
	Default map to be used. More...

#define	SYTEN_KTOY_MAPS
	Valid mappings for momentum→position maps, update if k_to_y::decideFunction() changes. More...

Typedefs
typedef Index(*	syten::k_to_y::MomentumFunction) (Index maxp, int k)
	Type of a function returning a momentum→position mapping. More...

Functions
MomentumFunction	syten::k_to_y::decideFunction (std::string const &fun)
	Returns a pointer to the specified function, update SYTEN_KTOY_MAPS if this changes. More...

Index	syten::k_to_y::linear (Index maxp, int k)
	The trivial mapping. More...

Index	syten::k_to_y::map_to_interval (Index maxp, int k)
	Maps the momentum k into the interval \( [0, maxp) \). More...

Index	syten::k_to_y::ordered (std::vector< Index > idx, Index maxp, int k)
	momenta ordered according to vector idx loaded from file More...

std::vector< Index >	syten::k_to_y::ordering (Index maxp, std::function< Index(int)> kfun)
	Returns a vector v[i], meaning that the i-th column has momentum v[i]. More...

Index	syten::k_to_y::sep_pi (Index maxp, int k)
	momenta separated by π (or maxp/2) are next to each other More...
