I'm trying the use the function 'knnsearch'. When I run the example code in the 'knnsearch' documentation (see, I get the following error:

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

Error in ==> Test at 7

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

Many thanks,
