Function Documentation

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

inline

Defines the packed size of a covariance matrices.

Definition at line 38 of file FieldBase.h.

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

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'.
