how do i reverse a vector

so far i have this

function [Vout]=reverse(Vin)

Answer 1

[Youssef Khmou]

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.

[Matthew Eicholtz]

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

[Andrei Bobrov]

wrev(vect) -> vect(end:-1:1)

please try:

>> open wrev

Answer 2

[Royi Avital]

This might work as well (For 1D Vectors):

vReversed = v(end:-1:1);

Good luck!

[Shweta Kanitkar]

v(end:-1:1) subtracts each element from v(end) by 1.

[Walter Roberson]

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

[Cyrus David Pastelero]

This is what I am looking for. Thank you.

Answer 3

[Walter Roberson]

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.

use fliplr()
