Hi Lóránt,
I understand you have a Simulink model and one of the outputs of “To Workspace” Block gives an unexpected result according to you.
Simulink automatically computes the appropriate sample rates for the blocks connected to the source blocks. You may notice “out.simout1” has a sample rate/period of 133.3333 . So, the block is sampled at the multiples of 133.3333 second and simulation stops at 160. Hence 133.3333 second is the last time it was sampled during the 160 second simulation.
Follow the link below to better understand sample rates and how to inspect them.
I hope it helps you.
