Hi, I have an array of data repeating 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
I need to find the locations where values equal to 1, 4, 7, 10 are found to create a subsample using those locations.
In this case it will be position 1 4 7 10 11 14 17 20 and so on.
Please, help! Thanks, Pavel

The function ismember is what you are looking for.
x=[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
y=find(ismember(x,[1, 4, 7, 10 ])),
