hi,
To reverse a vector try the function ' wrev' , here is an example :
r=wrev(1:4)
If you to control the degree of reverse/shifting try 'circshift' function.

I like this solution. Does anybody know how fliplr and wrev differ in this particular case? Is one more computationally expensive than the other?

wrev(vect) -> vect(end:-1:1)
please try:
>> open wrev

This might work as well (For 1D Vectors):
vReversed = v(end:-1:1);
Good luck!

Matt Eicholtz points out that Shweta's comment is incorrect; no subtraction is done, only indexing.

fliplr() or flipud()
... But I suspect this is a class assignment. You will need to use your knowledge of MATLAB indexing and looping to work out your assignments for yourself.
