sorting an array in a specific order

How would I sort array elements in ascending order based on how close they are to a specific value. For example if x=[1 2 2.5 3 4 5] and y= 3.4 how would I make x arrange as [3 4 2.5 2 5 1]?

x=[1 2 2.5 3 4 5]; y= 3.4;

[~,is]=sort(abs(x-y))

is = 1×6

4 5 3 2 6 1

x=x(is)

x = 1×6

3.0000 4.0000 2.5000 2.0000 5.0000 1.0000
