25 Mar 2012 COMBN (4.2) All combinations of N elements taken from the vector V. Author: Jos (10584)

@Marc, thanks for your interest and suggestions for improvement. Yet, for code compatibility (and fairness) you need to implement to inverse order step as well :-)
21 Feb 2012 lorentzfit1 LORENTZFIT1 fits a 1-parameter Lorentzian function to data (download includes LORENTZVAL1) Author: Jered Wells

The update is well done, as the function now contains an adequate help section as well.

You made a mistake in the lorentz function (in the code). It should read:
1 ./ (a .* (x.^2 + 1))

Happy to re-rate after an update!
08 Feb 2012 Average and remove duplicates from a matrix This function averages out duplicate values in a matrix and removes the duplicates Author: Mitchell Olson

This might be useful to some. However, you should a look at accumarray:

[u,i,j] = unique(A(:,1)) ;
A_avg_dup = [j, accumarray(j,A(:,2),[],@mean)] ;

In addition, you might revise your help section, so that it mimics ML standards (H1 line, used by LOOKFOR, a SEE ALSO line). Take a look at the help of any basic ML function for some inspiration.
02 Feb 2012 Shuffle Numbers Shuffles numbers in a given matrix or vector Author: Aamir Alaud-din

This functionality has been around on the File Exchange for years. For instance, you might take a look at my RANDSWAP function
http://www.mathworks.nl/matlabcentral/fileexchange/12621-randswap

or RANDMAT by Peter Bodin
http://www.mathworks.nl/matlabcentral/fileexchange/7203-randmat

Here is the rather trivial one-liner for shuffling any array X (numbers, ND, cell, string, whatever):

X(randperm(numel(X)) = X ;

which maintains everything, except the order!

Your help section is pretty good; I'd suggest you try to follow ML standards, e.g., by creatin a proper H1 line, and example, and a See Also section (take a look at the help of any of the main ML functions)

That was EXACTLY what I was looking for!
Many thanks

20 Apr 2012 getkey Get a single keypress (v1.3, jan 2012) Author: Jos (10584) Farhan

Hey everone!!
Can any one please provide me with a code of keydown function and keypress function.
actually what i want to do is that when a specific key e.g. up arrow key is pressed, the ball starts moving in a circle and keeps on oving uptil the key is pressed.
as soon as that key is unpressed, the ball stops moving in a circle.
 thanks in advance :)
