Dear All,

I have a table with 200 rows and 2 columns.

Now, I want to select 40 rows with step of 5. row 1 , 5 ,10, 15 ... 200. I try ramsample but it is randoms.

Could any one help me ?

table = randi(200,200,2) % create a maxtrix 1000x2

index = randsample(1:length(table),20)

result = table(index,:)

Let T be you table.

idx = 0:5:200  ;
idx(1) = 1 ; 
iwant = T(idx,:) ;
