The Runge--Kutta--Fehlberg method (denoted RKF45) or Fehlberg method was developed by the German mathematician Erwin Fehlberg (1911--1990) in 1969 NASA report. The novelty of Fehlberg's method is that it is an embedded method from the Runge-Kutta family, and it has a procedure to determine if the proper step size h is being used.
