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.
