Nowhere in your message did you show the error you received. Please show all the text displayed in the Command Window in red and/or orange when you execute that line of code.

My guess is that you called this function with a 3-dimensional or 4-dimensional A array like an RGB image.

The documentation for the medfilt2 function does state that its first input must be a "2-D grayscale image | 2-D binary image". Yours is not 2-D.
