RKErrorB

RKErrorB[rk]

computes the "B" measure of the quality of the embedded pair rk.

RKErrorB[rk,p]

assumes the order of rk is p.

Details and Options

  • RKErrorB[rk,p] computes , where is the order error of the embedded method from RKErrorA.
  • The order of rk should be one more than its embedding.
  • Ideally, a method of order should have so that the embedded method provides an accurate approximation of the error over a wide range of step sizes.
