I recently came across this command in an .m file
sim('kalmanfilter',[0 100],[],[0 20]);
it tries to run a simulink file "kalmanfilter" (located: http://www.mathworks.com/matlabcentral/fileexchange/18465-learning-the-kalman-filter-in-simulink-v2-1)
[0 100] is the time span of the simulation
[] ? i do not know what that is
[0 20] is the input to the model. I just do not know how simulink knows that [0 100] is the time-span or [0 20] is the input range. the help document does not help.
Thanks.

  • [0 100] is the time span,
  • [] - here you can put a option structure, which can modify simulation settings. You can change simulation setting by means of simset function,
  • [0 20] this is the external input to the model.

pemfir: You are using the backwards-compatible (older) syntax of the SIM command. See documentation here.
