I am trying to solve a boundary value problem, but I keep getting the above error. I know there are similar posts to this, but I can not seem to get this to work with them, so maybe someone can look directly at my code to get an answer?
The differential equation I want to solve is (putting it in first order form and wrting as a row vector): . Here:
I included my code as well and used to pick an inital guess. This is doing a bad job of that I think however! What else could I do here? Another inital guess, another function? Any help will be appreciated!

I mean to remember that this is a transformed equation with tanh to map (-oo,oo) to [-1:1].
Could you include the original equation as well ?
