Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I noticed such a strange behavior in my code every time I add a threshold: little oscillation around the threshold value itself.

For example

[tex] f(x) = g(x), x > x_c[/tex]

[tex] f(x) = 0, x <= x_c[/tex]

[tex]\frac{dx}{dt}=f(x)[/tex]

I solve the last equation and I find this oscillation. Can they be removed?
