The textwrap command is sufficient. As UIHANDLE you can create a temporary object, e.g. uicontrol('Style', 'text', 'visible', 'off') which get the appropriate dimensions.

How did you put that text over that axes control? Did you use the text() function, or is there a static text control on top of the axes?

If you have a text control, like Jan said, you can send your text string, and handle to your control, into textwrap() to get a text with line breaks in it that you can then send to the control with set().

myText = textwrap(handles.text1, reallyLongText);
set(handles.text1, 'String', myText);

Or, if you want to control where the breaks are, you can use sprintf():

myText = sprintf('Line 1\nLine 2\nLine 3');
set(handles.text1, 'String', myText);

You can also use sprintf() with the text() function.

It's well,Thanks Jan Simon and Image Analyst I get the picture by the code

     d=txt{2+loopi,4};
     h=uicontrol('Style','Text','fontsize',10);
     string ={d;{}};
    [outstring,newpos]=textwrap(h,string,45);
     set(h,'String',outstring,'Position',newpos);

And then

I add

      newpos(1)=370;
      newpos(2)=230;

But the question is the location is changing when I batch like this

Another option is wraptext.
