orceller is on a distinguished road
I am trying hard to numerically integrate a 4th order ODE using MATLAB solvers and I am unable to get it done.

Someone has already done it as reported in the paper and I cannot just understand how come they got it integrated using runge-kutta when MATLAB is failing.

I have uploaded the problem statement as attachment and can send the MATLAB as well as FORTRAN 90 code via e-mail (Its big as an attachment here.)

Any pointers will be gracefully accepted and appreciated.
