the reset and complement functions don't work even though I wrote the codes for them correctly
app.UIAxes.cla;
app.UIAxes2.cla;
app.img = "";
app.img2 = "";
app.img2 = imcomplement(app.img);
imshow(app.img2 , 'Parent', app.UIAxes2);

Not sure of your definition of "correctly". Yes, that won't give a syntax error, but it's not correct.
You are setting two global variables (fields of the global app variable): img and img2. These are set to the null string.
imcomplement takes an image variable as an input -- an actual numerical matrix, not a character string.

So how should I solve this problem?

Did you try just deleting these two lines:
app.img = "";
app.img2 = "";
If those fields are really image arrays, then it should work, once you don't redefine them to be null strings.
