Did you know about imgaussfilt()?

[Suresh Alluri]

yes but here the tricky part is not to use the inbuilt functions like imgaussfilt() or fspecial(), just to add on how to specify the grid size and domain : spatial for a filter??

Huh? Why? Why on earth would you not want to use a built-in function that makes your life easier??? Why put that restriction on yourself?

If you want to do it the hard way, go ahead -- I'm sure it's not hard or beyond your capabilities.
