Method Detail

transformTo

Hep3Vector transformTo(Hep3Vector vector)

Returns coordinates of a point in the transformed reference frame given its coordinates in the original reference frame.

transformFrom

Hep3Vector transformFrom(Hep3Vector vector)

Returns coordinates of a point in the original reference frame given its coordinates in the transformed reference frame.

transformTo

SymmetricMatrix transformTo(SymmetricMatrix covMatrix)

Returns covariance matrix in the transformed reference frame given the covariance matrix in the original reference frame. Throws RuntimeException if transformed covariance matrix cannot be computed based on the original covariance matrix alone.

transformFrom

SymmetricMatrix transformFrom(SymmetricMatrix covMatrix)

Returns covariance matrix in the original reference frame given the covariance matrix in the transformed reference frame. Throws RuntimeException if original covariance matrix cannot be computed based on the transformed covariance matrix alone.

transformTo

SymmetricMatrix transformTo(SymmetricMatrix covMatrix,
                          Hep3Vector vector)

Returns covariance matrix in the transformed reference frame given the covariance matrix and position in the original reference frame.

transformFrom

SymmetricMatrix transformFrom(SymmetricMatrix covMatrix,
                            Hep3Vector vector)

Returns covariance matrix in the original reference frame given the covariance matrix and position in the transformed reference frame.
