Transfer function and lsim

I know that the time response of an arbitrary input can be obtained using the lsim function. However, is there a continuous form of this function? Normally, we have to introduce a time vector with constant time steps to lsim so that it can calculate the time response. However, it seems it is different in SIMULINK, where the time response is calculated continuously. Does anyone know how SIMULINK does that and if it can be used in MATLAB as well or not?

lsim has the option for both contionous and discrete. When defining your input time vector decrease the time step to mimick a "continous" signal if you are experiancing discontinuties or other unwanted results. The difference compared to SIMULINK is that it is uses some ODE solver which deals with these time steps "behind the scenes" depending on which solver you are using.
