Error message for tspan in ode45
显示 更早的评论
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.

What values do your vectors for tspan have in your loop?

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]
