Revision 1.7, Fri Mar 8 04:54:01 2013 UTC (11 years, 3 months ago) by takayama
Branch: MAIN
Changes since 1.6: +7 -1
lines
New options: --strategy n --abserr e1 --relerr e2
If n==0, then the 4th Runge-Kutta is used.
If n==1, then the adaptive 4th Runge-Kutta is used where e1 is the absolute error and e2 is the relative error
to control the step size.
