This element simulates a sextupole using a matrix, up to third order.
The K1 and J1 parameters allow introducing normal and skew quadrupole error terms. The matrix expressions assume that these are weak effects and high accuracy should not be expected if this is not true. If K1 is significant, then use of the KQUSE element is preferred.
