Arrange element according to its index

Hi All,

Let's say we have arrays as follow: a=[3 4 5 6 7 9] b=[2 4 1 3 5 6]

in this case b acts as index of a. I want to form a new element x such that: x=[5 3 6 4 7 9] in which a is being arranged according to its index.

How can I do that? Appreciate your help.

Easy:

>> a = [3,4,5,6,7,9];
>> b = [2,4,1,3,5,6];
>> x(b) = a
x =
     5     3     6     4     7     9
