Solving differential equation by Matlab

Hello,

I am trying to solve a differential equation. I have already the General form of the solution, but I have to find integration constants.

PS: My equation is an order 7 and I have 7 BC, it is impossible to do it by hand.

Symbolically with DSOLVE or numerically with ODE45, ODE23, ODE113, ODE23s, etc.?

I already tried to do it, but I don't have initial conditions but baoundary conditions. One of them is an integral.
