sorry for the delay Mineralter, now it can handle figures and axes at the first argument!

then instead of manipulating the indices of the variable to the right of =, you manipulate the indices of the variable that receives value and it does not change the size of the vector! Interesting!!! Thank you so much for your contribution. I'll keep the function any way because it serves for for learning purposes!

of course, I should have thought of that at night I made the code!
I'll update right now! Thanks Jan Simon!

Use evaluateAlphaBetaParam to evaluates alpha and beta parameters so that the alpha-beta filter becomes a steady-state Kalman filter : http://www.mathworks.com/matlabcentral/fileexchange/42409

Another interesting point is the "linear indexing": x(end:-1:1) accesses all elements even of multi-dimensional arrays.

Please fix the documentation here and in the code: The vector of length N is:
[x(N), x(N-1), ..., x(1)]. It does not start at x(N-1).

The help section has a H1-line, a useful description of the procedure, and a See Also line. The file contains a change log and the name of the author. The actual code is nearly trivial, so I do not think, that this submission is very useful for others. Therefore I rate it with 4 stars instead of 5, although I do not see any point, where it could be improved.

The same command works for matrices and multi-dimensional errors also:

x = [1,2; 3,4];
x(end:-1:1) = x;
disp(x)
>> [4,3; 2,1]

This is much faster and simpler than the FOR-loop. In fact, it is such simple that I'd hesitate to create a function for it.
