I only have basic matlab knowledge, so the simpler the code the better! Something that would be easy for me to understand. Thanks!

Method zero: colon and times:
>> 6.*(1:16)
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96
Method one: mod and logical indexing:
>> v = 1:100; % any vector
>> v(mod(v,6)==0)
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96
Method three: linear indexing:
>> v(6:6:end) % v starts from 1
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96
Method three: colon:
>> 6:6:100
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96
Method four: cumsum:
>> cumsum(6*ones(1,16))
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96
Method five: rdivide, fix, eq, and logical indexing:
>> w = v./6;
>> v(fix(w)==w)
ans =
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90 96

16 is floor(100/6) -- which is to say the maximum number of full multiples of 6 that fits into 100.
