Your title is not an accurate description of your post. Your post is asking somebody to write specific code for you, not a general question about how to write a function.
If you have the Image Processing Toolbox, please look at imread.m, imnoise.m, and medfilt2.m.
There are examples there of filtering salt & pepper noise. medfilt2.m will handle various classes of input image.

@Esther: Please read the "Getting Started" chapters of the documentations, which is displayed by tyoing "doc" in the command window. Creating and calling a function belong to the very basics and a forum cannot replace a deep study of the documentation.
