1	Pass	filetext = fileread('summ.m'); assert(isempty(strfind(filetext, 'regexp')),'regexp hacks are forbidden')
2	Pass	v = randi(10, 1, randi(10)); s = summ(v); assert(length(s) == length(v) - 1) ans = 4 7 13 10 7 13 11
3	Pass	v = 1:10; s_correct = 3:2:19; assert(isequal(summ(v),s_correct)) ans = 3 5 7 9 11 13 15 17 19
4	Pass	v = [1; 2; 4; 4; 5; 8]; s_correct = [3; 6; 8; 9; 13]; assert(isequal(summ(v),s_correct)) ans = 3 6 8 9 13
