I need to add a text to a plot.
text(x,max(E),'it is inf')
and the length of x can be more than one. so I will get the error because the length of x and y (max(E)) are not matching. I want to form y by repeating max(E) with the size of x. For example if the size of x is 4, then I wan to have y=[max(E),max(E),max(E),max(E)]. What is the shortest way to do it?
I want to avoid for loop as much as possible.

y = repmat(max(E),size(x))
