I am getting a warning 'Warning: Failure at t=5.672199e-11. Unable to meet integration tolerances without reducing the step size below the smallest value allowed
(1.033976e-25) at time t.
> In ode45 (line 360) '
As a result of this warning message I am getting my graph missing. the last part of my graphic is missing. How can I fix this problem. Here I am adding the related part of my code.
options = odeset('RelTol',1e-1,'AbsTol',1e-10);
[tt,N]=ode45('Fd3gainsw',tt,NNo,options);
tt=3000x1 double
NNo=5x1

This is likely caused by a singularity in the ODEs. Can you show the equations?
