Converting an array of doubles to a string

112 views (last 30 days)
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()
