Detailed Description

Performs HYP smearing.

Hyp smearing: taking the definition from hep-lat/0103029 (http://xxx.lanl.gov/abs/hep-lat/0103029)

Allows for restricting smearing to hyperplanes orthogonal to a specified direction.

Note: the current implementation is aggressively inefficient

Member Function Documentation

void cps::AlgHypSmear::run (  void   )

Do the smearing. If an output file is specified in the CommonArg argument, then the smearing coefficients are written to the file. Precondition: The smearing coefficents should be set with set_c1, set_2 and set_c3. Reimplemented from cps::AlgSmear. Definition at line 638 of file alg_smear.C. References cps::ERR, cps::Fclose(), cps::Error::FileA(), cps::CommonArg::filename, cps::Fopen(), cps::Fprintf(), cps::Error::General(), and cps::AlgSmear::get_orthog().

void cps::AlgHypSmear::set_c1 (  Float  x  )  [inline]

Sets a smearing coefficient. Definition at line 258 of file alg_smear.h.

void cps::AlgHypSmear::set_c2 (  Float  x  )  [inline]

Sets a smearing coefficient. Definition at line 260 of file alg_smear.h.

void cps::AlgHypSmear::set_c3 (  Float  x  )  [inline]

Sets a smearing coefficient. Definition at line 262 of file alg_smear.h.

void cps::AlgHypSmear::smear_link (  Matrix &  link, int *  pos, int  mu )  [protected, virtual]

Smear a link. Parameters: link  The link to smear. pos  The coordinates of the link. mu  The direction of the link. Implements cps::AlgSmear. Definition at line 567 of file alg_smear.C. References cps::Alg::AlgLattice(), cps::Matrix::Dagger(), cps::dir, cps::Matrix::DotMEqual(), cps::Matrix::DotMPlus(), and cps::Matrix::ZeroMatrix().
