Not enough input arguments.

I am trying to create a mX1 matrix that is initialized with zeros.

this is what I'm doing:

predictions = zeros((size(Xtest,1)), 1);

m = the number or rows in the matrix Xtest.

I'm getting the following error:

It seems you are striaghtaway running the function predictknn using run button. You should not run/ call a function like this.

You have to see what are the inputs to the function and define those inputs and then call the function. In this case, I see that your function predictknn needs a input Xtest. First define your input variable.

Xtest = define your input here ;  
% no call the function 
out = predictknn(Xtest) ;
