     set(gcf,'windowbuttonmotionfcn',your_callback);

Isn't this function called on any mouse move over the
figure, rather then on mouse hover?

thanks

True, but within your_callback you can prime a timer that
fires your_hover_function after the specified hover period.

There is no specific hover event or callback.

Do you mean to start a timer for every mouse move event and
after the timer period ends to check whether the mouse is in
the same location? this sounds not really efficient...

No - you can use a single (persistent) timer object and
simply reset it upon every mouse move callback. The timer
will not be reset if the mouse does not move (=hover) and so
after several seconds of mouse non-movement, the timer
callback function will fire.

Thanks Yair, this is the solution I needed

There is a mouse-over for the more recent versions of Matlab: look up the uicontrol property 'TooltipString'.
For example: >>set(gco,'TooltipString','This is an unhelpful popup help message')
would give the current object the indicated message.
