how do you filter time data using an analog filter without Simulink simulation?

I have some oscilloscope data (a time vector and a data vector) and would like to simulate the results if I filter it using an analog filter. (Some of my data files may have varying sample rates). The mkfilt and other filter design tools are great, but most of the 'filter' commands run digital filters on data vectors. Other than running a simulink model and reading the time & data vectors in from the workspace, apply the filter, then saving the output, is there an easier method to run the through the continuous filter in an m-file script?

You cannot use an analog filter in MATLAB or any other digital (discrete) environment. All continuous (s-space) filters are converted to discrete (z-space) filters, implicitly or explicitly.

You can only use an analogue filter as an analogue filter by realising it in hardware.

Thanks for your comments and I realize that, but the SIMULINK environment solves the differential equations to simulate the analog world using a variety of solvers, running at iteration rates faster than the analog dynamics. I was wondering if there was that type of solver that could be called from a simple command.

If I remember correctly, Simulink is C code and then compiled at run time. That could explain the increased efficiency of Simulink blocks.
