What do you mean by EDO/EDP?
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.
