Using BVP4C for overdetermined system

  1. Aug 4, 2011 #1
    I have an overdetermined nonlinear system of ODEs:

    W' = f(c)
    c'' = f(W,W',c)

    and boundary conditions

    I can split up the equations into three first order ODEs, and solve numerically with Matlab. I would like to use bvp4c, but I believe I have too many boundary conditions. Is this correct? If so, what alternative approach should I take to finding a solution. And if not, what am I doing wrong? I have already implemented the shooting method which is very sensitive on ICs for convergence, so looking for alternative method.

    I've realised that I haven't declared any parameters, and thus introduce an extra dimension. This was the problem!
