[Help-gsl] design philosophy

[Gideon Simpson]

I'm working on a project that involves both numerical integration of a system 
of ODEs and the solution of nonlinear systems of equations, and I was wondering 
if there was a reason that the interfaces were not better unified.  In 
particular, the ODE routines take, as arguments, double arrays, while the 
nonlinear solvers use the gsl_vector data structure.  It's easy enough to map 
from one to the other, but I was wondering, why not have more consistency?
