MATLAB: How to get permutation of two halves of given numbers range 1 to n separately and then concatenate.

permuation of a given number in a range 1:n in two halves and combine

Ex:
suppose
n=10,
n1=1:5
perm(n1)=1,3,4,2,5
n2=6:10
perm(n2)=6,8,7,10,9
perm(n)=concatenate(n1,n2)=1,3,4,2,5,6,8,7,10,9

Best Answer

>> n=10
n =
    10
>> [randperm(n/2), n/2+randperm(n/2)]
ans =
     5     3     4     2     1     7     9    10     8     6
