Implementig user-define function in Simulink

Hi

I'd like to use m-file function (custom Kalman filter) in my Simulink model. Witch block of User-Defined functions is more suitable for implementation? Can I use Embedded MATLAB Function block in this case?

Yes, you can use Embedded MATLAB function. But if your M-function is already done and you don't need to generate C code for it, you can use your M-function directly using the "Fcn" block or "MATLAB Fcn" block.

In addition, you may interested in looking at a comparison of the various uder-defined blocks available: http://www.mathworks.com/help/toolbox/simulink/ug/bq3qcgr.html (Subsystem and C-MEX S-function don't apply to your case)
