Hello,
Using matlab, I have to write a function which takes in an input matrix and flips the first and last values of the row. I CANNOT USE FLIPLR AND THIS MUST BE VECTORIZED! NO ITERATION OR SELECTION IS ALLOWED! This has to be done for either an odd or even numbered matrix. So, this needs to work for [1 2 3; 4 5 6; 7 8 9] and make it [3 2 1; 6 5 4; 9 8 7]. Similarly, it has to work for [12 13 14 15; 21 22 23 24; 31 32 33 34] and make it [15 13 14 12; 24 22 23 21; 34 32 33 31]. Any help will be appreciated! Thank you!

Hint: you can use "end" to refer to the last index, including doing arithmetic such as end/2
