Hi all;
While using ode45 with a pre generated time vector taken in a loop, i get the error message :
The entries in tspan must strictly increase or decrease.
Error in ==> ode45 at 173 [neq, tspan, ntspan, next, t0, tfinal, tdir, y0, f0, odeArgs, odeFcn, ...
Any guidance or reference to docs on this error would be helpful.
Thanks, Nani.

You get this error when your timespan is incorrectly set up.
Example of incorrect timespan:
[0 0]
[0:0.01:10 9]
Correct version:
[0 10]
[0:0.01:10]
