Subject: K-nearest neighbor search

Hello,

I'm trying the use the function 'knnsearch'. When I run the example code in the 'knnsearch' documentation (see http://www.mathworks.com/help/stats/knnsearch.html), I get the following error:

----------------------------------------
??? Undefined function or method 'knnsearch' for input arguments of type 'double'.

Error in ==> Test at 7
[n,d]=knnsearch(x,y,'k',10,'distance','minkowski','p',5);
-----------------------------------------

Please could you try run the code in that link, or perhaps suggest why I'm getting this error?

Many thanks,

Graham
