Clip

Force every entry of a matrix to lie within a given (half-)interval.

Implementations

Lower clip

Force every entry to be at least lowerBound.

C++ API

void LowerClip(Matrix<Real> &X, Real lowerBound = 0)

void LowerClip(AbstractDistMatrix<Real> &X, Real lowerBound = 0)

C API

ElError ElLowerClip_s(ElMatrix_s X, float lowerBound)

ElError ElLowerClip_d(ElMatrix_d X, double lowerBound)

ElError ElLowerClipDist_s(ElDistMatrix_s X, float lowerBound)

ElError ElLowerClipDist_d(ElDistMatrix_d X, double lowerBound)

Upper clip

Force every entry to be at most upperBound.

C++ API

void UpperClip(Matrix<Real> &X, Real upperBound = 0)

void UpperClip(AbstractDistMatrix<Real> &X, Real upperBound = 0)

C API

ElError ElUpperClip_s(ElMatrix_s X, float upperBound)

ElError ElUpperClipDist_s(ElDistMatrix_s X, float upperBound)

ElError ElUpperClipDist_d(ElDistMatrix_d X, double upperBound)

Interval clip

Force every entry to lie within the interval defined by lowerBound and upperBound.

C++ API

void Clip(Matrix<Real> &X, Real lowerBound = 0, Real upperBound = 1)

void Clip(AbstractDistMatrix<Real> &X, Real lowerBound = 0, Real upperBound = 1)

C API

ElError ElClip_s(ElMatrix_s X, float lowerBound, float upperBound)

ElError ElClip_d(ElMatrix_d X, double lowerBound, double upperBound)

ElError ElClipDist_s(ElDistMatrix_s X, float lowerBound, float upperBound)
