## The Best Way

The best way to reverse a vector is probably as follows:

Say we have a vector,

- test = [1,2,3,4,5]

and we want to reverse the numbers to provide us with a new vector:

- newVector = [5,4,3,2,1]

To accomplish this without using a while loop or for loop, we can simply use the variable 'end', that is predefined in matlab:

- newVector = test(end:-1:1)

What this statement say is take the last element of test ('end'), place that in the first element of newVector, then take the next last element of test ('end - 1') and put it into the second element of newVector, and so on, until newVector is a reversed copy of test. ** This method works with both row and column vectors**.

## Other Ways

Use the function flipud(vector) to reverse a column vector quickly.

- >> flipud([1;2;3])
- ans =
- 3
- 2
- 1

Use the function fliplr(vector) to reverse a row vector quickly.

- >> fliplr([1,2,3])
- ans =
- 3 2 1
