vector order inversion in Matlab

[claudiocamera]

I am working in a code and I need to invert the elements order of a vector, for instance I have the vector [ 1 2 3 4 5] and I need the vector [5 4 3 2 1] I was wondering that probably there is a function specifically for peforming this task ...

if x is your vector

len = length(x)
idx = len:-1:1

x = x(idx)

problem solved

There many other ways.
It may be simpler to use this:

x=x(end:-1:1);

hope it helped.

fliplr([1 2 3 4 5])

Sometimes the only way to find functions like that is to browse these MATLAB Help sections:
Help -> Contents -> MATLAB -> "Functions - By Category"
Help -> Contents -> MATLAB -> "Functions - Alphabetical List"

Be sure to read the "See Also" section at the bottom of the function description.
