About the ODEPACK differential equation solver used by mrgsolve
C---------------------------------------------------------------------- C This is the 12 November 2003 version of C DLSODA: Livermore Solver for Ordinary Differential Equations, with C Automatic method switching for stiff and nonstiff problems. C C This version is in double precision. C C DLSODA solves the initial value problem for stiff or nonstiff C systems of first order ODEs, C dy/dt = f(t,y) , or, in component form, C dy(i)/dt = f(i) = f(i,t,y(1),y(2),...,y(NEQ)) (i = 1,...,NEQ). C C This a variant version of the DLSODE package. C It switches automatically between stiff and nonstiff methods. C This means that the user does not have to determine whether the C problem is stiff or not, and the solver will automatically choose the C appropriate method. It always starts with the nonstiff method. C C Authors: Alan C.
