Hello,

My matlab code of ODEs has issues of integration tolerances. Here is the Warning:

Failure at t=4.061827e+01. Unable to meet integration tolerances without reducing the step size below the smallestvalue allowed (1.136868e-13) at time t.

However, matlab still keeps working and output all the results. I wonder if I can trust this result since it has a warning about integration tolerance?
