The Fehlberg RK1(2) method for ODEs.

The Fehlberg method has two methods of orders 1 and 2.

It has the characteristics of:

  • method stage = 2

  • method order = 1

  • Butcher Tables:

\[\begin{split}\begin{array}{l|ll} 0 & & \\ 1 / 2 & 1 / 2 & \\ 1 & 1 / 256 & 255 / 256 & \\ \hline & 1 / 512 & 255 / 256 & 1 / 512 \\ & 1 / 256 & 255 / 256 & 0 \end{array}\end{split}\]
