MATLAB: Calling variables instead of values

Question

I have this:

A=1; B=2; C=3;
x = [2 3 1]

I want to call x1 as:

x1 = 
    B     C     A

I can call individual values, but I don't know how to call them as variables.

Answer 1

xc = num2cell(x)
[B C A]= xc{:}

ADD

x = [2 3 1]
xc = {'A' 'B' 'C'}
x1 = xc(x)
