I am trying to classify some data with the use of the function knnclassify. However i got the following error when i use the m-file : ??? Error: File:

knnclassify.m Line: 119 Column: 1 The input character is not valid in MATLAB statements or expressions.

class = knnclassify(sample, training , group); is the commnad i use where sample is a matrix 2000x20 training 2000x20 and group 2000x1. Any idea about what is wrong in my case????

Show the group line 118-120 of knnclassify.m:

dbtype knnclassify.m 118:120

Also show the group which knnclassify function you're using:

which -all knnclassify

and the version of MATLAB and Statistics Toolbox you're using:

ver % Snip out the license number and all lines except MATLAB and Statistics 
Toolbox

My guess is that you have a different version of knnclassify.m on your path 
and/or you accidentally typed something into that function when you had it 
open in the Editor.
