I have a vector with daily data. I need to average every 7 values of it to obtain a new vector with weekly data.

As you mentioned in your comment, you have a vector of type double. In that case, you can average 7 elements as follow:
x = rand(1000,1); % random data
x = padarray(x, [ceil(numel(x)/7)*7 - numel(x) 0], 0, 'post'); % make sure that number of elements are multiple of 7
mean_x = mean(reshape(x, 7, []), 1)';

Fernanda, the second x does not need to be the same, your code is correct. But you will get an error because you are giving extra spaces between function name and the input arguments. This is generally not a problem, but it will cause an error when done inside [ ] brackets. So change the third line
time_series3 = padarray (time_series1, [ceil(numel (time_series1) / 7) * 7 - numel(time_series1) 0], 0, 'post' );
