Select multiple ranges from a column and insert these into new column

It can be done as follow,

• Generate the required indexes

interval = 55;
difference = 1066-170;
ind = [];
current_ind = 170;
while current_ind+difference<38529
  ind = [ind current_ind:current_ind+interval];
  current_ind = current_ind+difference;
end

• Extract required values from the old vector

new_vector = old_vector(ind);
