What timestep does my ode15s solver use?

i'm having the following issue: while using ode15s solver, it seems that during some moments the time step is too big, resulting in a huge spike. See attachment.
Hence I'd like to find out what step sizes are used at that moment, to see if I can prevent these spikes by using MaxStep with a value lower than the currently used one.

Assuming you call ode15s with [t,y]=ode15s... then you can just use
which will show you the difference between each of the time points (aka the time step length). Or
will show you the largest time step.
