I want to design a gui. And when the cursor point to different part of the GUI, I want it to change the shape itself. Such as becoming a cross or a hand when the cursor point to the image.

iptSetPointerBehavior(obj,pointerBehavior)

along with

iptPointerManager(hFigure,'enable')

can be used to automatically change the pointer symbol when it hovers over certain objects within the GUI. In regular figures, the pointer manager is supported with figure | axes | uipanel | image objects. As of r2020a, the pointer manager can also be used with uifigures but it seems that only uifigure and uiaxes are supported plus any object plotted within the axes (see demo).

% Change mouse pointer (cursor) to an arrow.
set(gcf,'Pointer','arrow')
drawnow;  % Cursor won't change right away unless you do this.
% Change mouse pointer (cursor) to an hourglass.  
% QUIRK: use 'watch' and you'll actually get an hourglass not a watch.
set(gcf,'Pointer','watch');
drawnow;  % Cursor won't change right away unless you do this.
