Variable step Fehlberg’s Method –example
Problem B2 from W.H. Enright & J.D. Pryce (Two Fortran Packages For Assessing Initial Value Methods, ACM Trans. On Mathematical Software, Vol. 13, No. 1, 1987, pp 1-27) was solved using the Variable-Step Fehlberg’s method. The equations are:
The initial conditions are 1 for all equations, with α= 3. A TOL of 1E-4 was used for the calculations, with Maxbound of 1.1 and Minbound of 0.9. The results are shown below:
