I try to implement median filter in FPGA with matlab, but in the step ''verify with cosimulation" i got that error "vector port is not currently supported. turn on hdl code generation option "scalarize vector ports", and then re-generate hdl code". when I turn on this option the simulation doesn't finish . please can you help me to know what's I need to do.

I suspect that you are sending in the entire frame of video into the median filter at one shot. I suggest you stream the video in, one pixel at a time to the median filter.

Here is an example of how we use pixel streaming in Simulink to median and image filters for noise removal. This is an example in MATLAB.
