Error in weightedVoting (line 27)
res(i,predict_label(i)) = res(i,predict_label(i)) + heus(1);

This is a simple error. You are trying to extract more number of elements then present in the array.
% Example
A = rand(1,5) ; % size of A is 1x5
A(1) % no error
A(4) % no error
A(end) % no error, this will give you 5th element
A(6) % error, there is no 6th element
Like wise check the dimensions of each array and use looping.

A predicted label might exceed the number of actual labels.
Or heus might be empty, if some of the other variables are empty.

k is the maximum label, which is a scalar. length(k) is 1. You use length(k) as the upper bound for the size of res so res is 120 by 1 instead of 120 by the number of labels
