'Set' function applied on handle and vector of handle

Hi everyone!

Here is a quick shot of a current optimization problem: Let's assume we have a vertical vector of handles. Each handle have been produced by executing the 'plot3' function, and each corresponding curve is defined by two points (twice {X Y Z}).

 h(1) = plot3([44 55],[0 0],[0 0],'-r'); hold on,
 h(2) = plot3([66 77],[0 0],[0 0],'-r');
 h(3) = plot3([88 99],[0 0],[0 0],'-r');
 h = [h(1);    % vector of handle
      h(2);
      h(3)];

Thus:

 get(h(1),'XData')

gives

 ans = [44 55]

ie the two x values of the two points of this curve

Then:

 set(h(1),'XData',[11 0])
 get(h(1),'XData')

gives

 ans = [11 0]

Whereas:

 set(h,'XData',[[11 0];
                [22 0];
                [33 0]])

causes

 Error using ==> set
 Value must be a column or row vector

Here comes trouble, I would like to update all XData properties of each handle in a single command, without making a loop. Is there any solution to that?

Thanks you very much for any kind of help, I am scratching my head on that since days!

Try

set(h,'XData',{[11 0];
               [22 0];
               [33 0]})

Okay just found it!

 A = [11 0;
      22 0;
      33 0];

 set(h,{'XData'},num2cell(A,2))

And by the way thanks Walter, your tip to add {} is equivalent to num2cell. But then {} around 'XData' also have to be added.
