Converting an array of doubles to a string

Whats the best way to convert v which is a class double.

v =

           0           0        2736        1824
ans =

    'double'    

I tried this

            v=vidobj.ROIPosition      %Get default ROI
            class(v)
            nv=numel(v);
            strROI='';
            for i=1:nv
                strROI=strROI+char(v(i))
            end
            strROI

I want to display it in an editbox

            app.Edit1.Value=strROI

How do you want it displayed?

v=[0,0,2736,1824];
d=num2str(v);%once it is a character array you can manipulate it as you desire use sprintf() or regexp()
