The numbers on the listbox do not look the way I want.

my kod:

set(handles.listbox1,'String',x,'FontSize',12);

x = 3.71044e+06

How can I show it as "x =37104445.345"?

Show what? In the code you have shown you define x after you set it, but since the content of a listbox is a string it will show up exactly as you tell it to. The format used for a number on the command line has no effect over that. You haven't shown what you do to get the x that goes into the listbox.

I get "x = K2 + dx/10000;" with this function and it prints the result.

That still doesn't add anything to the question really. You set a string in the list box. Where is that string defined? Your x there is numeric so you must turn it into a string and how you do that will determine what is shown in the listbox.

Try this:

x = 3.71044e+06;
s = sprintf('%.3f', x); % Turn x into a string.
handles.listbox1.String = s; % Send string to the listbox control.

Set the fontsize in GUIDE rather than code if you want it to be the same all the time.
