Octave provides two solvers for differential equations. lsode : For ordinary differential equations (ODE) of the explicit form y' = f(x,y) dassl : For differential algebraic equations (DAE) or implicit ODE of the form f(y', y, x) = 0 Prime (') implies derivative wrt the the dependent variable x. However, I use RADAU5 from a C-programmed and find it faster, and use Octave just verify the results of my code. Vivek...
