Reversing element order in a selected sub sequence?

Two positions are selected randomly then element positions between these two positions are reversed.

For example: A = [1 2 3 4 5 6 7 8 9 10]; idx = randi(10, 1, 2) = [3 8]; 'A' will be become A = [1 2 8 7 6 5 4 3 9 10]

Thank you

A([1:min(idx)-1,max(idx):-1:min(idx),max(idx)+1:10])
