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:
Thank you in advance.

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) ;
