You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sumv.m
    path of file: ./repos/bnt/KPMtools
    
    the code of the file until where you have to start completion: function T2 = sumv(T1, sum_over)
%
% Like the built in sum, but will sum over several dimensions and then squeeze the result.


    
function T2 = sumv(T1, sum_over)
%
% Like the built in sum, but will sum over several dimensions and then squeeze the result.

T2 = T1;
for i=1:length(sum_over)
  if sum_over(i) <= ndims(T2) % prevent summing over non-existent dimensions
    T2=sum(T2, sum_over(i));
  end
