Function Documentation

computeCovariancePackedSize()

int lsst::afw::table::detail::computeCovariancePackedSize ( int  size )

inline

Defines the packed size of a covariance matrices.

Definition at line 35 of file FieldBase.h.

{ return size * (size + 1) / 2; }

indexCovariance()

int lsst::afw::table::detail::indexCovariance ( int  i, int  j  )

inline

Defines the ordering of packed covariance matrices.

This storage is equivalent to LAPACK 'UPLO=U'.

Definition at line 32 of file FieldBase.h.

{ return (i < j) ? (i + j * (j + 1) / 2) : (j + i * (i + 1) / 2); }
