how to choose some rows from a matrix randomly in turns? I mean increasingly counter. for example if data is [1,2,3,4,5,6,7,8,9] the random choosing needs to be [1,4,5,7,9], but not [5,1,7,2,4]

I am not certain what your criteria are.
See if this does what you want:
v = [1,2,3,4,5,6,7,8,9];
idx = randperm(length(v), 5); % Choose 5 Elements Randomly
random_choosing = sort(v(idx)) % Random Elements (Sorted In Ascending Order)
random_choosing =
2 4 6 7 8
