Matlab (EditField Function)

Hello, iam currently developing Fuzzy logic image processing system to detect edges in an image in matlab. so far, i only can change the value of sx and sy in command line to detect edges. (picture 1)

but i want apply it on this function (picture 2) and i dont know how to do it.

This is my code
classdef Sugoi < matlab.apps.AppBase
