MATLAB: Flip an array with the use of vectors

arrayflipMATLABvectors

I would like to flip specific cells in an array, not the whole array, with the use of vectors. For example a=[1 7 5 9 3 2 4 1] and i want to flip it from 5 to 2 and make it a=[1 7 2 3 9 5 4 1]. Any suggestions? Thank you in advance.

"Any suggestions?"
Use indexing (which in MATLAB starts from 1):
>> a = [1,7,5,9,3,2,4,1]
a =
   1   7   5   9   3   2   4   1
>> a(3:6) = a(6:-1:3)
a =
   1   7   2   3   9   5   4   1
