while solving a particular non-linear problem using ODE 45, the following message is obtaing for some values of control parameters, for others the program is working properly. How to fix this error?
Warning: Failure at t=2.215676e+01. Unable to meet the integration tolerance without reducing the step size below the smaalest value allowed(5.684342e-14) at time t.
In ODE 45 at 308.

The error message can have many reasons: singularity of the solution, stiffness of the ODE system, too high or low values for the tolerances (RelTol ans AbsTol) or a simple programming error on your side.
We will have to see your MATLAB coding to give more specific advice.
Best wishes
Torsten.

since it is related to my unpublished work I can't reveal the program, if you guarantee secrecy will send to your email,(if email Id is given)
