Undefined function or variable

I am getting the following error:

this is the function call:

 k_distances,k_indices = findKNN(classifier,Xtest(i:1,:));

and this is the first line of the function definition:

 function [k_distances,k_indices] = findKNN(classifier,x_test)

can anybody see what I did wrong here?

Thank you

When you want to return results from a function, if there are more then ONE output, use square brackets.

[k_distances,k_indices] = findKNN(classifier,Xtest(i:1,:));

Just like the function header.
