Sorting an array and their corresponding

kinda stupid question but I couldnt figure it out,

I have two arrays, say

a = [5;10;1]
b = [0.1;0.2;0.3]

Now I am trying to sort the first array using sort and I want the corresping elements in array b sort with their corresponding element in a them, so if I do

sort(a) 

I want the output to be

a = [1;5;10]
b = [0.3;0.1;0.2]

The corresponding elements in element b should stick with their original elemnt in a.

Any help is greatly appreciated.
