How to implement 'Medfilt1' function into Simulink

Hello everybody,
unfortunatelly I'm not finding the equivalent Simulink block of 'Medfilt1' function implemented in Matlab(R2010a).
Have you any suggestion to solve this problem?
I heard the possibility to use S-function in order to get an embedded Matlab function into Simulink, also if I don't know how I can do that.
Any advice is well accepted.
Thanks in advance.
Regards.

do you have the option of incorporating command windown options in it and link a M file to your mdl?

If you have the Video and Image Processing Blockset, use the 2D median filter and change the "Neighborhood size" to 1xN or Nx1 (depending on the format of the 1D vector you're feeding in).

If you do not have the tool box then you'll probably need to use the S-Function feature you mentioned (although I have personally never used it). There are examples that come with Matlab for those that can be browsed through the Simulink UI. I don't believe Simulink offers other methods for non-linear filtering (at least not for 2009b).
You might be able to figure out a more convoluted method using the 'sort' block from the signal processing toolbox, but using the s-function will most likely be faster or at least less frustrating.
